Car at 25ft, picture taken at 10ft |
60ft from opposite wall. This angle shows how far my car is away from the wall. |
Car parked 220 ft away. Picture taken from 220 ft. Even at this distant, the blue cutoff line is still concentrated. Note how the cutoff beam run along the green bushes along the left side. It's hard to see since the beam is shining on something dark. Keep this in mind when comparing with other beams. Also pay attention to the trash-bin wall which is about 50ft away. There's 6 parking spaces between my car and the wall. |
This a map from Google's Earth. There's a built-in tool which allows you to draw a line and Google will determine the distant pretty accurately. That's how I determine my distant. The green spot indicate where I take my photo. |

Right-side view at 40 ft |
Closeup view at 25 ft |
RX330 with clear lens at 220 ft; cutoff beam is soft, but you can still see the blue color band; at the 50 ft trash bin wall, it is soft; although the RX330 is wide on the left side, it is not bright enough to appear on the green bushes. |
RX330 /w TSX lens and oem shield vs. zTail; you can see the zTail beam on the left side along the green bushes. You'll have to look closely to see it. |
RX330 with TSX clear lens to increase clarity. |
RX330 with zStep shield mod. How you align and position the shield will affect output. |
Car at 25 ft; picture taken at 40 ft; The stadium light makes the beam less intense than it really is. With a curve shield, the RX330 beam stretch onto the side building. |
Right-side view. Car at 25 ft; picture taken at 40 ft. Beam is sharp and straight. Rich blue color in the center. |
Front view at 25 ft. |
Close up shot at 5 ft. You can see the entire blue band all the way to the end. It looks thin but it's there. |
Close up shot at 10 ft. |
Shield is re-positioned to obtain multi-color; very nice. |
Another angle at 5 ft; car still parked 25 ft. |
At this angle, you can see that concentrated streak of light stretched to the side wall. |
At this angle, you can see that rich, thin and sharp blue color band, ideal for flicker effect as the car bounces. |
Front view at 25 ft. |
Left-side view at 40 ft; at this distant, you can barely see the colors on the cutoff, but in person it's clearly visible. |
Right-side view at 30 ft; while some people want more diluted blue color, I like it thin and concentrated. |
Modded RX330 vs. zTail at 25 ft. Picture is blur. Keep in mind that the RX330 beam overlap the zTail beam, making it less clear. |
Left-side view at 40 ft. At this angle, you can see that heavy streak of light on the RX330 right-side step. See how it crosses onto the other building. The skylight is coming from the zTail, not the RX330. |
Right-side view at 30 ft. |
Car at 25 ft; picture taken at 60 ft. At this perspective, you can see the entire beam spread. |
Modded RX330 beam at 220 ft. |
RX330 on top and zTail on bottom; Note how the RX330 run along the side building. Note how the zTail run along the green bushes. |
SC430 OEM textured lens. In terms of clarity, it's worse than polk-a-dot or ripple lenses. |
SC430 OEM curve shield; can't be removed or bent. |
Car at 25 ft; picture taken at 5 ft. Multi-color band is obscurred by the SC430 soft lens. |
Front view; car at 25 ft; picture taken at 25 ft; straight and bright, but very soft |
Left-side view at 40 ft; you can see the beam spread onto the side building; but it's very soft. The stadium lighting further make the beam appear faded. |
Right-side view at 30 ft. |
SC430 on top vs. zTail on bottom; SC430 appear to slop down as compare to the zTail perfectly straight beam. |
Car at 25 ft; picture taken at 60 ft; at this perspective, you can see the sc430 slop downward on the left side. Both beams have about the same width. Picture is over-exposed. |
SC430 OEM beam at 220 ft. So soft, you can barely see the slent step. |
SC430 OEM beam on top vs. zTail beam on bottom; zTail beam stand out better; you can clearly see the concentrated blue color band; good foreground; nice spread to the left side on the green bushes. |
TSX clear lens swap for better clarity. |
SC430 with TSX clear lens; still using oem curve shield. |
Left-side view; car at 25 ft; picture taken at 40 ft. The sc430 beam now stand out better; very sharp and straight; now you can clearly see the beam spreads onto the side building. |
Right-side view at 30 ft; nice thick blue color band in the center |
Closeup view at 5 ft; entire picture is blur, as noted by the door hinges; otherwise very nice |
5 ft at another angle; you can see the spread on the side wall; a bit too much blue in the center for me. This can be adjusted by re-positioning the lens away from shield. |
By re-positioning the TSX lens, you get a more thin and concentration blue color band. |
Front view; car at 25 ft; picture taken at 10 ft; I aim the beam higher so you can see the bottom portion of the beam which is chopped off, due to a shield on the lens holder which limited foreground output. This is for safety reason. HID beam is meant to give better output at further distance. A very bright foreground will cause your pupil to close, thus you can't see light at further distance. This defeats the purpose of installing HID projector. When it come to safety, oem sc430 and oem acura tl have the best design. But I'm more interested in look. |
Front view comparison; car at 25 ft; picture taken at 10 ft; SC430 on top vs. zTail on bottom; SC430 has too much blue, but can be reduced and condensed simply by re-positioning the lens. |
Left-side view comparison at 40 ft; very clean on both beams. |
Car at 25 ft; picture taken at 60 ft, showing entire beam spread. |
Modded SC430 at 220 ft; blue color band clearly visible; sharp and clean on the trash-bin wall too. |
Comparison at 220 ft; clear lens SC430 on top vs. S2K zTail on bottom. |
Front view; Car at 25 ft; picture taken at 25 ft; With intensity increase; note the concentrated streak of light on left side |
Right-side view at 30 ft; the concentrated streak of light will penetrate even at far distant; this is ideal if you want to see your beam spread and bounce on the road; this will set your beam apart from other OEM beams. |
Close comparison between SC430 on top and zTail on bottom; Car at 25 ft; picture taken at 5 ft. Very nice and thin blue color band; good streak of concentrated light on left side step |
Front view at 25 ft |
Right-side view; car at 25 ft; picture taken at 30 ft; both beam are straight, clean, sharp, and evenly spread below cutoff. |
Left-side view at 40 ft; stadium light overlaps beams on the side building, making cutoff less visible; otherwise, very visible. |
TSX with OEM clear lens |
TSX with OEM curve double indentation shield. |
Front view; car at 25 ft; picture taken at 25 ft; There's a rainbow band above the cutoff, as well as blue flair on the right upper step. |
Closeup shot at 5 ft, lacking color on the cutoff |
Closeup shot at 5 ft; the TSX is really good, even though it doesn't show it here. |
Left-side view at 40 ft; very wide and fairly sharp |
Right-side view at 30 ft; |
Right-side view comparison at 30 ft; TSX on top vs. zTail on bottom; TSX is as wide and sharp as zTail |
Left-side view comparison; car at 25 ft; picture taken at 50 ft; at this distant, you can see the entire beam spread; very nice. |
TSX beam at 220 ft; lacking color, but remains sharp; on the trash-bin wall at 50 ft, it is sharp like the zTail beam. However, it is not as bright as zTail; note the TSX beam doesn't show up on the left side on the green bushes. |
TSX with zig-zaq shield mod. The shield has to be perfectly straight and horizonatally flat to get a nice straight beam. |
Another angle showing shield |
Car at 25 ft; picture taken at 30 ft. TSX shield mod above vs. S2K zTail shield mod on the bottom. TSX is sharp and wide as the zTail. However, it is not straight. It has smile face. I intentionally tip the shield forward, which causes the beam to slope upward. This can be easily fixed by re-adjusting the shield. |
Car at 25 ft; picture taken at 60 ft; at this perspective, you can see the entire TSX beam slope upward and also the huge flair. |
Left-side view at 40 ft; I tilt the shield perpendicularly straight, which results in a straight beam. Nice and sharp beam. TSX has a good amount of concentrated blue on the center, but begin to flair up away from the center. |
Right-side view comparison. The TSX appear to have more definition than the zTail, but that'only because it overlap the zTail, making it less distinctive. |
TSX alone at 30 ft; shield repositioned to reduce flair |
Close-up shot at 5 ft. |
Close-up shot at 5 ft. All blue color band, lacking purple. |
Shield re-adjusted to get extra purple and reddish orange. |
Comparison between TSX and zTail; the TSX shield is re-positioned to reduce the flair. The flair is very hard to eliminate, but is do-able. |
Car at 25 ft; picture taken at 60 ft; at this perspective, entire beam spread can be seen. TSX beam above is very straight, sharp, and clean. As wide as the s2k zTail below. |
TSX shield mod at 220 ft; beam remains very sharp and distinctive, even with that stadium light just above it. The stadium light is broken, hence the greenish color. |
TSX vs. zTail; on the TSX, note how the blue color band is softened and flairy, whereas the zTail has a more concentrated blue band. If you look closely, you can see the cutoff along the green bush. |
Audi A6 with OEM ripple lens; this type of lens softens the cutoff beam |
At this angle, you can see the ripples in the lens. |
A6 OEM straight shield. There's actually a little curve in the center. |
Car at 25 ft; picture taken at 30 ft; Beam is very soft and not bright; the ripple lens dissolves the otherwise nice blue color band; it also has irregular hot spread and beam is not evenly spread below the cutoff. |
Closeup shot at 5 ft; the A6 has lots of color, but they're all softened. Doesn't look too good. |
Car at 25 ft; picture taken at 30 ft; at this angle, you can see that the beam is very short. The left side of the beam doesn't reach the end of the building, and the left side of the beam stop short at the corner. |
Left-side view; Car at 25 ft; picture taken at 40 ft; The beam doesn't cross the side building; very blurry. |
Left-side comparison view; A6 on top vs. zTail s2k on bottom. zTail clearly stand out; it is straight, wider, sharper, and brighter. Camera fails to pick up the intensity different. |
Right-side view; A6 on top vs. s2k zTail on bottom; The A6 appears to have lot of blue, but it is really a diluted blue when seen in person. |
A6 with TSX clear lens; this will give clarity and definition to the otherwise soft beam |
This angle shows clarity of the lens. |
A6 oem straight lens. |
Front view; Car at 25 ft; picture taken at 25 ft; Big different when compare to the ripple lens shown above; Beam is much sharper and you can see the multiple color along the cutoff. Beam is not evenly distributed below the cutoff. |
Car at 25 ft; picture taken at 5 ft; Nice purple and blue color; Image is kinda blur, as noted by the door hinges. |
Another angle at 5 ft |
Left side view; Car at 25 ft; picture taken at 40 ft; at this angle, you can see the entire beam spread, which is still short; the clear lens doesn't make much different in terms of wide. Because of the OEM shield, the cutoff is sharp in the center, but become soft toward he the sides. Note the streak of light on the two sides which are not directly below the cutoff. They are sloping downward. |
Right-side view; car at 25 ft; picture taken at 30 ft |
Comparison view; A6 on top vs. zTail on bottom. A6 has good concentration blue/purple color along the center of the beam. A6 has two streak of light which are sloping downward beneath the cutoff, wheras the zTail have them directly on the cutoff, which makes the s2k beam more visible as you drive down the road |
Right-side view; car at 25 ft; picture taken at 40 ft; at the angle, you can see a big different in spread between A6 and zTail. |
A6 with TSX clear lens at 220 ft. Beam remains sharp and visible; you can still see the blue/purple color band. |
Comparison at 220 ft; A6 on top vs. zTail on bottom. Both look good; A6 is less intense when seen in person. zTail has really good forground |
A6 with TSX clear lens and curved shield mod |
Front view |
Z-shape curve shield; doesn't work with A6 projector to increase width as you'll see below. This is due to the design of the projector bowl which doesn't throw light to the outside edges of the shield. |
Front view; car at 25 ft; picture taken at 25 ft; Has good concentration of blue and purple color band on cutoff. Flair on upper step is eliminated. |
Close-up shot at 3 ft; |
Left-side view; picture taken 25 ft from center of beam; blue/purple band covers most of the entire beam |
Right-side view at 10 ft; car at 25 ft; Lots of color along the cutoff line. |
Right-side view at 30 ft; car at 25 ft; at this angle, you can see the entire beam; the beam is still short; the curve shield mod doesn't help with increasing width. The design of the projector bowl is the culprit. |
Comparison view at 30 ft; modded A6 vs. zTail sk2 on bottom; both beams look straight; A6 has irregular hot spot while zTail is more evenly distributed. |
Left-side comparison at 40 ft; car parked at 25 ft; at this perspective, you can see that the A6 has a very short width in comparison to the zTail s2k which stretch onto the side wall. The A6 curved shield mod helps increase the concentration of light along the side cutoff line. This will make the beam more visible along wall as you cruis down the road. |
Comparison view at 220 ft; A6 on top vs. zTail on bottom; A6 looks very similar to zTail, however, s2k is wider and more intense |
A6 by itself at 220 ft; forground is not that bright; however the A6 curve shield mod helps increase brightness along the cutoff, as witness by the light along the green bushes which is lacking with the OEM straight shield. Look closely and you'll see the contrast of the bush and the beam. |
BMW X5(e39) projector with OEM ripple lens and oem straight shield |
At this angle, you can see the ripples in the lens which make the beam soft |
X5 OEM straight shield; there's actually a curved identation in the center; but not a fully curve to produce wide beam |
Front view; car at 25 ft; picture taken at 25 ft; X5 has a mixture of nice reddish orange and blue color in the center however the ripple lens softens the color as well as the cutoff line; it get even softer on the sides. |
Close-up view at 5 ft; |
Left-side view; car at 25 ft; picture taken at 30 ft; beam looks good in the center, but begin to fade quickly on the sides; beam is very short; light is not evenly spread below cutoff |
Front view comparison at 25 ft; X5 on top vs. zTail s2k on bottom; X5 is fairly straight, but lacking color, sharnpess, and intensity |
Right-side view at 30 ft |
Close-up coomparison view at 5 ft; zTail s2k is very colorful; the x5 overlaps the zTail beam, making it less sharp and less rich in color (see zTail beam by itself above) |
Left-view comparison; car at 25 ft; picture taken at 25 from center of cutoff; at this perspective, you can the zTail stretch onto side wall while X5 barely reach the corner; on the left side, zTail has that concenration of light below the cutoff while x5 is softened. |
Car at 25 ft; picture taken at 60 ft |
X5 projector with curve shield mod and OEM ripple lens |
I replaced OEM straight shield with a curve shield to increase width, but the X5's less convexed lens restrict the width increase; you will need a curve shield along with a more convex lens like the TSX lens (see X5 /w clear lens and curve shield) |
This angle show how I mount the moded shield. |
Right-side view; car at 25 ft; picture taken at 30 ft; curve shields helps with color along cutoff, but doesn't increase width; ripple lens soften cutoff |
Left-side comparison view; car at 25 ft; picture taken at 40 ft; zTail looks clean, wider, and has even spread below cutoff |
Right-side view; car at 25 ft; picture taken at 40 ft; |
X5 with curve shield and oem lens at 220 ft; beam is soft but visible; limited forground lighting |
X5 vs. zTail S2K at 220 ft; s2k is much brighter and better foreground |
X5 (e39) with TSX clear lens |
At this angle, you can see that the smaller TSX lens are held by 3 handi-tak rubbers; I find this rubbers very useful |
Clear lens with OEM straight shield; shield is semi-curve but not fully arched. |
Car at 25 ft; picture taken at 25 ft; very clean, sharp, colorful, and concentrated in the center, but note how it quickly dissolved on the sides; this has to due with the oem straight shield |
Left-side view from 220 ft; at this angle, you can see how the more convexed TSX lens helps the beam spread onto the side building; too bad the oem straight shield fail to give it definition; a curve shield will solve it (see section below) |
Car still at 25ft; picture taken at 5 ft; very nice and clean in the center; note, x5 beam is not intense when seen in person |
Right-side view; Car at 25 ft; picture taken at 30 ft; I re-positioned the TSX lens to give the beam more more. |
Close-up at 5 ft; by repositioning the lens, you can achieved more concentrated blue; you can get even more, but blanded blue, but that's not my kind of thing |
Close-up shot at 3 ft; |
Front view comparison, X5 on top vs. zTail S2K on bottom; At 25 ft, you don't see the entire beam spread, as such, the x5 look as though it is as wide as S2K; look very clean on both beam, but s2k is more intense and colorful. |
Left-side comparison, Car at 25 ft; picture taken at 40 ft from center on beams. zTail beam stretches all the way to the side wall. You can barely see the X5 cross the side building. |
Car at 25 ft; picture taken at 5 ft; |
Car at 25 ft; picture taken at 5 ft from wall and 25 ft from center of beam; |
X5 with TSX clear lens and OEM straight shield at 220 ft; lacking color and inttensity |
X5 vs zTail at 220 ft; Note the intensity of the zTail on the trash bin wall in comparison with the X5. |
Top view of X5 with TSX clear lens and curved shield for maximum output |
Side view; TSX lens is held mid-air with handi-tak rubber; to be used temporarily for testing |
Top-side view so you can see how the shield is being positioned |
Front view; car at 25 ft; picture taken at 25 ft; very clean, sharp, and good concentration of blue color band |
Left-side view at 40 ft; at this angle, you can see beam spread onto the side building; if it wasn't for the stadium light, the beam would be more visible. |
Close-up shot at 5 ft; really nice and rich blue color band |
Front view at 25 ft; This time, I re-positioned the shield to achieve those reddish orange and purple color. |
Close-up shot at 5 ft; car at 25 ft; good concentrated multi-color band. |
Car at 25 ft; picture taken at 60 ft; at this perspective, you can see the entire beam spread; very nice, wide, and even. A combination of more convexed TSX lens and curved shield help increase the width. |
Comparison view; car at 25 ft; picture taken at 35 ft; modded X5 beam looks just like zTail minus the tail and minus the intensity. This shows that bigger lens doesn't mean more intensity than smaller lens. |
Left-side comparison; car at 25 ft; picture taken at 40 ft; Look exactly the same in width and sharpness. S2K has that streak of concentrated light on side cutoff which is lacking on X5. |
Right-side comparison at 10 ft; The blue color band on X5 seem duller in comparison to zTail which is more colorful; This is because X5 is dimmer. |
Car at 25 ft; picture taken at 60 ft; |
Modded X5 vs zTail S2K at 220 ft; very similar pattern; |
Modded X5 at 220 ft by itself; note the foreground intensity as well as the intensity at 50 ft trash bin wall. |
An '04 BMW ZKW clear lens bi-Xenon projector. The projector body is made of plastic! |
The projector has a very thin, straight cutoff shield. The shield is attached to a high-beam mechanism which create a chopping action, causeing the shield to go down, and produce high beam. |
This is a 3" clear lens with a single notch on the rim to prevent the lens from rotating on the lens holder. Note the bottom of the lens, there's a horizontal indentation which cause light to bleed above the cutoff. |
Car at 25ft, picture taken 40ft away on the left side. Cutoff very clean and colorful in the center, but quickly softened and faded on the sides. |
Car at 25ft, picture taken 40ft away on the right side. Only look good in the center. Beam is very short. |
Car at 25ft; Picture taken at 25ft. Picture doesn't show the entire beam. The cutoff beam has some flair just like the TSX. |
Close-up at 5ft. Really nice and sharp slant cutoff. The reddish-orange on the lower step is beautiful. Only bad part is the side. |
Comparison with S2K zTail. Car at 25ft, picture taken at 40ft. BWM 330 zkw beam is more colorful in the center, but it has some hot spots. zTail S2K beam is much cleaner and evenly spread, and sharper throughout the entire cutoff. |
Car at 25ft, picture taken 32ft behind car. This angle show hows quickly the 330xi beam become faded and soft on the side. |
.Car at 25ft, picture taken at 40ft on the right side of car. On the center of the door, is a white paint over someone's grafitti. That not part of the beam. |
Car at 25ft, picture taken at 25ft. zTail beam is brighter and more evenly spread. |
Closeup shot at 10ft. Look really nice up-close for both beam. |
Car at 25ft, picture taken at 50ft, showing entire beam spread. |
330xi ZKW beam vs. zTail S2K at 220ft. Both beam is clearly visible. Note how the 330xi beam doesn't run along the side wall like those other projectors. |
330xi ZKW beam alone at 220ft. Note the foreground is not a bright as S2K, and the cutoff beam at the 50ft trash beam wall is very soft, compared to the S2K which is brighter and sharper. |
The TSX lens is smaller. So I temparorily use 3M sticky rubber to hold the lens in place. This rubber is a good product to help me easily test and adjust the lens for focusing purpose, but one should use circular carboard rings for spacing. |
At this angle, you can see that the TSX lens is placed closer to the oem straight shield. |
Closeup shot at 5 ft. Car is parked 25ft away. Very nice and colorful in the center, just like oem ZKW lens. |
Car at 25ft, picture taken at 23ft. Look good in the center, but quickly become faded on the side. The flair above the cutoff beam is more noticable than compare to oem ZKW lens. |
Car at 25ft, picture taken at 40ft from center. At this angle, you can see the entire beam. Beam is so nice, sharp, and colrful in the center, but the sides is not so pleasing. |
Comparison pictures between lens swap 330xi and zTail S2K. Remember taht zTail beam is enclosed inside the headlight while the 330xi is in nake form outside the headlight. |
Car at 25ft, picture taken at 25ft. The slant step on the 330xi is twice in height compared to the zTail step. |
Car at 25ft, picture taken at 40 ft at an angle from the left side of car. This angle show how the zTail beam spread onto the side wall. It's more clearly visible and sharper. |
A closeup shot at 10 ft. |
Another close-up shot at 10 ft at an angle. The TSX lens swap produce a rich deep blue in the center. |
Car at 220ft, picture taken at 220ft. TSX lens swap 330xi still look sharp at 220ft. |
330xi with TSX lens swap at 220ft. Foreground is not a bright as S2K. Also at the 50ft trash bin wall, you don't see the cutoff line and it's less bright. |
BMW 330xi projector with TSX clear lens and curved shield mod. TSX lens is held against projector lens holder using 3M sticky rubber. |
At this angle, you can see the curved shield. A curved shield along with a more convexed lens help increase beam width. |
I attached the modified curved shield onto the oem movable shield. There are two clips on the oem shield which holds the add-on curved shield tightly. |
Car at 25ft, picture taken at 30ft. Referencing OEM 330xi beam, this beam is wider, flatter, yet maintain color and sharpness in the center. |
Car at 25ft, picture taken at 40ft. Nice purple color in the center. |
At this angle, you can see the cutoff extends to the side wall, however it's very weak. |
Here's a center shot at 25ft. Camera could not take entire beam spread at this distant. 330xi is weaker in comparison. |
Here's a side comparison with zTail S2K. Car at 25ft; picture taken at 5ft from center. 330xi beam is wide as zTail. |
Comparison with zTail S2K. Car at 25ft, picture taken at 40ft on left side. zTail S2K is brighter overall and has more definition along cutoff thanks to its concentrated streak of light along the cutoff line. |
Car at 25ft, picture take at 5ft from an angle. Picture is a little blue. 330xi beam has nice rich blue/purple color. |
Car at 220ft, picture taken at 220ft. Modded 330xi beam on top. You can still see the blue color band. Note how the cutoff beam run across the side building. This was lacking on the OEM 330xi beam. |
Modded 330xi beam alone. Note the trash bin wall at 50ft, the cutoff line is visible which was lacking on 330xi OEM. Compared to the zTail S2K, it is less bright. |
Side view of TL projector |
3" ripple lens. Has similar diameter and convexity as X5 and 330xi lenses. A ripple and less convexed lens will yield a soft and narrow beam. |
TL has a movable shield which flip down, yielding a high beam. The shield is semi-curved. |
Car at 25ft, picture taken on left side at 40ft. Colorful and bright in the center, but softened. Sides are very blur and soft. |
Car at 25ft, picture taken on right side at 40ft. Good concentration of light in the center. Multi-color but softened by ripple lens. |
Closeup shot at 5ft while car at 25ft. |
Closeup comparison with zTail S2K. Car at 25ft, picture taken at 5ft. |
Car at 25ft, picture taken at 40ft on left side. At this far angle, zTail beam stand out better, has more definition along the cutoff, and wider. |
Closeup comparison at 5ft, showing right-half of cutoff. |
Car at 25ft, picture taken at 25ft. Showing partial beam spread. TL beam is sloping downward a little. zTail is straight and even. |
Car at 25ft, picture takend at 40 ft on right side of car. TL has a big hot spot that look like a spaceship. zTail S2K is more evenly spread and run along the side cutoff line. |
Car at 25ft, picture taken at 27ft. TL is softer on side and narrower. |
Car at 25ft, picture taken at 60ft. |
Car at 220ft. TL on top. |
TL by itself. There's no distinctive cutoff line on the trash bin wall at 50ft. |
Since the TSX lens is smaller in diameter and convexity, it will require a different spacing from the cutoff shield. This is accomplished with layer of spacers which is made of cereal box. Simply trace out the lens and cut it. I used 12 cereal box spacers, which give you a deep purple color in the center. 13 spacer if you want the beam to be more yellowish-orange. 11 spacer if you want more blue |
This is how it look from the inside. Essentially, you spacing the lens closer to the cutoff shield. I use 3M sticky rubber to temporarily hold the lens against the spacers. I can easily remove the sticky rubber to add more or less spacers during testing. |
This is how the projector look at from the front with the TSX lens and spacers. |
Car at 25ft, picture taken at 40 ft from left side angle. TSX lens swap help with sharpess and width. Lens is correctly spaced to get nice purple color. Also, note the 'spaceship' concentrated light in the center. The more convexed TSX lens help spread the spaceship wider. If you reference the OEM TL beam, you can see the difference. |
Car at 25ft, picture taken at 25ft. Beam is slope downward just a little. |
Closeup shot from right angle at 5ft while car is at 25ft. Nice reddish purple colors in the center. |
Comparison with zTail S2K. Car at 25ft, picture taken at 40ft from left side. At this angle, you can see the entire beam spread. Note how the TL beam is now much wider and has more definition. |
Car at 25ft, picture taken at 30ft. The TL now reaches the end of the wall, and is also brighter. zTail S2K is still sharper. TL is sloping downward a little. A shield mod will fix that as you will see later. |
Car at 25ft, picture taken at 10ft from center. TL is now as wide as S2K, but has less definition. |
Car at 25ft, picture taken at 60ft. This angle show the entire beam spread. TL is sloping downward a little, as most OEM beams are. Shield mod easily fix that. |
TL with TSX lens beam at 220ft. The purple color band is still visible. Note the cutoff on the trash bin wall at 50ft. |
Comparison to zTail at 220ft. The TL foreground brightness is as bright as zTail S2K, only difference is that the S2K cover more immediate area. |
TL projector with TSX clear lens and curved shield mod. |
Here's a shot showing the curved shield. The shield is made up of two flash sheet which allow me to adjust the height, depth, and rotation without bending the shield up or down. The TL has lot of hold where you can screw the shield onto the projector. I temporarily use green painter tape for testing. |
Here's another closeup angle showing at 45 degree downward. |
Car at 25ft, picture taken at 5ft. Really nice, clean, and sharp. Love the concentrated thin blue color band. |
Car at 25ft, picture taken at 40ft from right side. Beam no longer sloping downward. Straight and clean. Still a little soft on the outer edges. |
At 40ft from the left side. Beam spread onto side wall. |
Car at 25ft, picture taken at 30ft. Showing left-half of beam. Beam stretch all the way to end of wall, and still clearly visible. |
Comparison with zTail S2K. TL beam is a little brighter at the end, but note the concentrated streak of light on the S2K's cutoff. |
Car at 25ft, picture taken at 25ft. Picture only show partial beam spread. |
Car at 25ft, picture taken at 10ft from center. This angle show both beam has the same width. |
Car at 25ft, picture taken at 35ft from right side. A combination of clear lens swap and curved shield mod make a nice and wide beam. |
Car at 25ft, picture taken at 60ft. This angle shows the entire beam spreads. |
Comparison at 220ft. Note how the TL cutoff run along the side buidling. Note the zTail S2K cutoff run along the green bushes. In person, you can see it better. |
Modded TL beam at 220ft. The color band still remain blue at this distant. Note the cutoff beam run along the green bushes. |
Here, I used 12 spacers which give me more purple. |
This is at 25ft. The purple color will become blue at long distant. |
Side angle at 7ft. |
Here, I used 13 spacer which give more yellow. |
The beam still remains straight and even. |
At 220ft, the yellow color will turn into purple. It's hard to see 'cuz my camera can't handle picture clearly at that distant. |
This is a 330xi ZKW clear lens. You can use 1 or 2 spacers, or no spacer. Spacer can be easily made out of cereal box. The number of spacers used will determine the color band. |
I'm swapping out the lens but keeping the TL OEM semi-curve shield. |
TL projector with ZKW lens and OEM shield. |
Car at 25ft, picture taken at 40 from right side. Here's I use no spacer. The colorband is yellow/orange. The yellow will become purple at long distant. |
Car at 25ft, picture taken at 25ft. Doesn't look impressive up close. |
Comparison with zTail S2K. Picture taken at 30ft while car at 25ft from wall. TL/ZKW is a little shorter and a little softer on the side edge. S2K is brighter along the cutoff line. |
Car at 25ft, picture taken at 40ft from left side. Picture is a little blur. Here, you can see the entire beam spread. |
Here's a closeup shot showing the side. TL /w ZKW is a little shorter. |
TL /w ZKW at 220ft. The cutoff is purple at 220ft. Forground is good, but it covers a smaller area due to TL foreground limiter. The cutoff at the 50ft trash bin is sharp and clean. |
Comparison with zTail S2K, which cover more foreground. The cutoff on the 50ft trash bin is brighter compared to TL/ZKW. |
Here, I used 1 spacer which give the cutoff that deep concentration purple colorband. Car at 25ft, picture taken at 40 ft from left side. |
Car at 25ft, picture taken at 30 next to car. Really nice in the center. Sharp and has a nice deep purple color. Side cutoff is a little soft. |
Comparison with zTail S2K. Car at 25ft, picture taken at 40ft from right side. TL has that spaceship concentrated light in the center, but week on the side. S2K has evenly spread in the center and has better definition along cutoff line. |
Closeup shot showing the side wall. S2K is wider. |
Car at 220ft, picture taken at 220ft. Modded TL on top, zTail on bottom. TL beam become blue at long distant. |
Modded TL alone at 220ft. Sharp cutoff on the 50ft trash bin wall, but become soft at the end. |
Here, I used 2 cereal box spacers to get the blue color band. Car at 25ft, picture taken at 25ft. |
Closeup shot at 5ft while car is at 25ft. |
Another closeup shot. Picture taken at 10ft from center. The cutoff is sharp in the center but become faded and soft on the side edge. |
The colorband is still sharp and remain blue at 220ft. Note the trash bin wall at 50ft. The sharp cutoff become very soft at the end. |
330xi ZKW lens inside a TL lens holder. You can use 1 or 2 cereal box spacers or none. I recommend 1 spacer. |
Replacing the TL semi-curve shield with a fully curved shield. Shield is sharp and straight. Same shield used with TSX clear lens swap. |
Here's a closeup shot at another angle. Shield is made of two flash sheets held together by screw, washer, and nut. This allows me to move the shield forward/backward while keeping the shield straight. You don't want to bend the shield backward which creates a frowning cutoff, or bend the shield forward which create a smiling cutoff. |
Car at 25ft, picture taken at 27ft next to car. Here's I use 1 spacer to get the nice purple/blue color. |
Car at 25ft, picture taken at 40 from right side. Beam look very clean, sharp, and has a thin concentration of purple colorband in the center. |
Closeup shot at 5ft showing side angle. Nice color in the center. |
Comparison with zTail S2K. Sharp and clean for both beams. zTail is a little wider. S2K lens is more convexed than ZKW lens. zTail beam has that unique streak of light along cutoff which not visible on TL/ZKW. |
Picture taken at 40ft while car is 25ft from wall. Both beams look great. Remember, zTail is enclosed inside headlight while TL/ZKW is naked. |
Car still at 25ft, picture taken at 5ft from center. |
Car at 25ft while picture taken at 40ft from left side. At this angle, you can see the beam spread onto the side wall. S2K is wider and also brighter. On the TL/ZKW, there's a hot spot that look like a spaceship. It's bright in the center, but become weak beyond the center. Because of the big contrast difference, it make the center look much brighter than it's really is. |
Car is 25ft and picture taken at 25ft. This angle only show partial beam spread. Nice concentrated purple/reddish color on TL/ZKW. You can tell a different in intensity between zTail S2K and TL/ZKW. |
Closeup shot showing side wall. Car at 25 while picture taken 5ft from center. The modded TL has a very nice and rich color band. Remember, I use 1 spacer which sit between the lens and the lens holder. I'm essentially moving the lens about 1mm away from the cutoff shield. |
Here's a big picture of the spread. Car at 25ft, picture is taken 25ft from the center on the far left. At this angle, you can see the zTail concentrated streak of light on the left cutoff. On the side building, you can see the zTail beam is wider too. In the center, s2K is more intense. Remember that the s2k is enclosed inside headlight. |
Car at 25ft, picture taken at 60ft. At this angle, you can see the entire beam spread from side to side. |
Modded TL beam at 220ft alone. Colorband become blue. Note the sharpness at the 50ft trash bin wall. |
Here, I used 2 spacers to get blue colorband. Car at 25ft, picture taken at 25ft. |
Closeup shot at 5ft while car parked at 25ft. Thick blue colorband. |
Car at 25ft, picture taken at 40 from left side. Cutoff beam look clean and straight. The trend is getting more color (blue color). I recommend a thin, sharp, and concentrated colorband. |
This time, I use no spacer, which give a yellow/orange colorband. Since the ZKW lens is about 1mm smaller in diameter, you may want to add some 3M rubber around the edges to position the lens in the center and prevent movement. |
Closeup shot at 25ft, car parked 25ft. The 'Z' in the center look kinda fuzzy at 25ft, but at 40ft and further, it become sharper. |
Car still at 25ft while picture taken at 5ft from center. Note the thin blue colorband just away from the center.. |
Comparison with zTail S2K. TL above and S2K on the bottom. Note the sharp TL/ZKW running along the side building. The TL 'Z' shape now look sharp and the yellow become purple. |
Modded TL at 220ft alone. The fuzzy yellow 'Z' (at 25ft) now look sharper and purple at 220ft. The cutoff on the trash bin wall is straight and clean. |
