    yeah only the euro versions came with clear lens, and i believe most hid projectors over there did as well. we americans have some strange and outdated ideas about lighting lol. also remember the valeos were one of the first hid projectors and now close to 15 yrs old as far as the technology goes. still for their time they have an excellent cutoff and beam. a bit too much foreground compared to other units, but decently bright and wide. i got stuck with them due to my aftermarket housings where valeos were literally the only projector that would fit without any modding. but with everything cleaned up and new bulbs, they are very nice on a dark road. should hold me over until led headlight modules become cheaper and more available. i would certainly recommend osram svs or cbi bulbs for these projectors if you need more light but dont want to risk going to 50w ballasts or different projectors.

The recent threads in the B6 section concerning lens swapping where very anticlimactic in that the results were certainly not apparent that all the effort involved in a lens swap made a serious difference. Better? Yes. But IMO not worth all the effort.

    Regardless, that thread in the B5 section has a stellar amount of info and is perfect for many of the B5ers suffering from decreased light output (for whatever the reason). Point being, for most of them anything new (including lenses) will be better than the original projectors + housings.



    Good to know, I'll pass that along to some friends interested in this retro.



    gearbox, I fully agree that there are so many factors that can affect light output and subsequently pictures of it. This is rarely brought up (even more so outside of HID Planet) and should be more often. When I discovered my OEM housings were fairly dirty on the inside (both outer cover and projector) it occurred to me that many ppl who'd switched from DOT housings to newer, far cleaner Ecodes were also noticing a difference due to their condition.

    Also, the B5 S4 HIDs do come with clear lenses. Unsure if those were Euro spec only or DOT as well, but that's been verified an documented on Audizine.
    All U.S. B5 S4 projectors use a Fresnel lens (non frosted) All Valeo Euro projectors for the B5 S4 are clear with a purple tint. So in my case I saw almost no difference in light output against a wall but I still feel that the sharp cut off helps when you're driving, unless it's just in my head haha. I can see going from a frosted lens to a clear lens making a huge difference though.

    I agree about the sharp cutoff... Ecode housings make all the difference. As for the lenses, I've never seen the comparos in person but perhaps a better way of saying it was that considering the build up in some of those threads, the before / after pics of lens swaps looks rather underwhelming. Again, they appeared to be an improvement over the stock B6 lenses but when pressed for a concrete evaluation most of the guys who'd done it stated there was marginal improvement at best. However, in a previous model with older equipment the change would certainly be more apparent. Hope that makes more sense. Bottom line, if I had to pull my housings apart and knew replacement lenses would be a direct fit + no focal issues (if that's the term) I'd likely do it anyway. Any improvement is worth it to me.

    The best thing you can do for an "older" Audi projector is clean the lenses. They are always coated in dirt by this age.

    Before I swapped out my halogen DOT projectors, I did notice the lenses were dirty and frosty within the inside. Been using E-codes for awhile now, though not as new as projectors of today, they do light up a 5 lane highway pretty well, though the light intensity does fall off a bit at the extreme wide edges. I can only imagine what the other drivers are thinking when I pull along them or pass them and they can no longer see their headlights on the road anymore. CBI bulbs are great, though I would like to compare them somehow to the all LED headlights of the new A6,7, and 8.

    Couldn't agree more. And this is even more so with mine as the housings weren't properly sealed for a while. Real bummer. At this time I'd rather not experiment on the housings and open them up. Perhaps over the summer when they're replaced.

    It's comments like this that are making it difficult for me to be patient installing mine... Ecodes are sitting right here on my table. ;-) But I want to get new door seals and check for any leaks as they're kinda old. Well, that and wait for the CBIs to arrive.

    I'm assuming you got the single xenon ecodes?

    Yup! Really stoked. CBI's just arrived along with some Osram 65w H7's for highs and LED city lights w/built in resistors. I want to get some new seals for the doors though, so they're not quite ready to go in yet.

    Sadly, not yet. I still need to order rear doors - to acquire some new seals - and equally important address a slight internal haze in the pass side Ecode. I'm going to have to pull the internals, rinse the housing out and re-seal the body... something I'm really not looking fwd to.
