Bi-X: W203/CL203 OEM Bi-XENON Upgrade, Auto-Levelling & Programming thread
yeah i know its different in europe, but hids are different in the states as well. ECE hids tend to be clear with a sharp cutoff..creating clear cut offs and good intensity from a distance and up close.
US DOT hids tend to have frensel or diffused lens to make them bright from a distance then get less intense as you get closer. The cut off is also not as sharp and more diffused.
Before they made clear lens replicas, people use to buy ece lens and swap them out in the US hid projectors because it would make the beam sharper and brighter.
Taken from my argument with e1000 thread.
European ECE e46 projectors

US DOT version of the same projectors

Also keep in mind he has a US 350z where as you have a UK one. You guys pay in pounds, what we pay in dollars..i figure you deserve more features right?..

As a result, my left headlight is out of whack: it points a bit higher than the right.
I have a decent opportunity to buy a set of used bi-xenon, incl. "control-units".
Do you know how much is plug&play and how much is "re-engineering the whole concept of the car" in an upgrade from xenon to bi-xenon?
- power supply?
- auto-balancing/levelling
- recoding (activating certain codes in) the computer?
- ?

Doesn't change my attitude that Auto leveling should be mandatory for safety reasons & I like the European solution.I know exactly what your photos are trying to show but they really suck at it. Different circumstances - different exposures. Hardly comparable

OK, sounds good. Has Frank W(iesmann, right?) posted any info on this? I cannot find it anywhere...

I'm not disagreeing with you, but back to what splinter was saying, it doesnt make to sense to try to add a feature that can be up to half the value of the car when just having them aimed correctly can be a sufficient substitute.
I've had my tsx projectors since april without autoleveling. I've never been flashed and most people can't tell there non oem until i drive up next to them at night and my lights are brighter then theres since i'm running 55watt ballasts..

I followed the link in your first post and found all the info I needed. (I guess I was not the first one with this problem :-)
I have ordered the bi-xenons now: W203, 2003; 320 EUR.
Thanks & BR

I do try to use American English on the forum as I worked for an American Oil Company for 37 years & understand the problem. I substitute trunk for boot & hood for bonnet etc.
Under our education system the use of American English & spelling even to this day will ensure you are marked wrong, wrong, wrong!
Anyone else have a problem understanding me? Do you have trouble understanding Splinter? He is one person on this forum that uses good English (British perspective)
My roots are British/Canadian

Also keep in mind the auto leveling only works effectively if your driving slow over dips or the dips gradual or around corners. I know the bmw ones turn around corners with the steering, not sure if the mercedes one does the same.
If you go over a bump quickly the auto leveling won't have time to adjust fast enough anyways.
Most roads in the US are pretty flat anyways, at least around large cities and most of the mid west.

You can still get flicker and glare when you go over a hill or long dip.
Have you never gone down a small dip and a car follows behind you with hids and the light from the car following behind turns blue or purple for a second in your rear view mirror when the car is coming up on the upward part of the dip.
situations like that auto leveling will elminate distractons like that. Why do you think the EU requires them by law.

I said:
You're on the right track but you're a bit misguided. The blue or yellow hues are determined by where the cutoff shield is in relation to the projector focal length. You can bend the shield a bit to get a more bluer or yellower cutoff. Again, the autoleveling isn't fast enough to react to things like bumps in the road.
Plus.....I'm pretty sure all factory HID equiped cars must also be auto-leveling and have a headlamp washing system
And then you replied:
Flicker is glare from the cut off when it hits the human eye, usually via bumps in the road. The human brain only has a second to determine the color, so it picks the color thats dominates at the time from the color spectrum of the cut off.
perfect example would be a ap1 s2000. Drive in front of a 2000-2004 s2000 on a bumpy road and you will understand what i mean. The stock cut off is white, but when it flickers, it flickers blue, purple and yellow.
Your are incorrect on the auto leveling. Auto leveling was specifically designed to keep the cut off at stock level to prevent flicker. Flicker looks great, but can be distracting to other drivers on the road since its a form of glare, hence why its considered a safety feature and only come on hid lights not halogens.
Manufacturers have replaced clear lens with fresnel ones to soften the cut off and reduce flicker.
I believe it might be required to have auto level lights in Europe. I know its not required in the US. The s2000 and last gen tsx did not have auto leveling lights.

Mr. Stern’s treatise regarding glare.
The vast majority of professionals in my neighborhood pilot vehicles originally equipped with xenon lighting. As they bobble along our pockmarked streets, encounter a dip in the road and rebound, or crest a rise, their high-end lighting is readily identifiable to any enthusiast and, I suspect, most mundane commuters. They should not project untoward glare during steady-state conditions, but instances when it occurs are a given – as with any headlamps.
I’ve personally helped a bro fit bi-xenons to his W203 which was originally equipped with halogen lamps. Not long thereafter, my frosty OE xenons were ditched for proper European-specification bi-xenons. It’s a kick to watch them cycle through their aiming limits from high to low against the garage wall before settling in on their preprogrammed focal point upon startup. Nonetheless, they’ve necessitated mechanical aiming and sensor adjustments as it’s gone through its various suspension and ride height (rake) iterations during my stewardship. Several stateside have completed similar upgrades. Most are responsible and mature representatives of the marque, as their lamps are correctly aimed downward from the static point of origin. There is not, as I understand it, any dynamic aiming capability whist underway with our chassis, save for those equipped with MB’s aiming thumbwheel adjacent to the headlamp switch.
It is not a realistic or sensible ROI to insist one retrofit MB’s leveling paraphernalia during a HID upgrade, as doing so would require an expenditure approaching or exceeding half the market value of the entire car in many instances. One should insist that they be aimed correctly with due respect to fellow motorists and then be on his merry way. IMHO, of course.
I hate having to read the drivel that Mr. Glyn Rick puts out. Even on ignore I end up seeing his posts....
I'm the lucky guy that Splinter helped to install the Bix. Correct aiming is no more difficult than aiming a standard light. The light output of bix to halogen is beyond compare and worth the money. I mean, look at my mod list.
While I did not know that it was a federal law to have the leveling system, I have taken great measure to monitor the light pattern of my bix and adjust accordingly.

My main disagreement with you was lack of recognization of color at the cut off, flicker and that there performance differences between different hid projectors.
Comparing most OEM Xenon and OEM Bi-xenon projectors is like splitting hairs. They are all generally of high quality and 99% of the people out there don't give a crap about color and sharpness of cutoff, beam pattern, etc between OEM projectors. What does matter is when people use re-based bulbs in halogen reflector housings or even worse, aftermarket projectors like the ones made by Depo.
You didnt know the differnce until I had to show you the difference with the videos.
I believe the new g35 projectors are stanleys.

movie of the flicker,
as you can see the cut off changes to different colors, outside of the tuned purple.
The effects are more apparent and distinct when you see them in person.

i dont even understand why you want to keep thread hi-jacking other people's threads by talking about a dead argument.
I don't know why you keep on trying to bring it up on almost every lighting thread.
