Pm sent.

I sell my products local and world wide .. Sometime I just don't post to this site...

Btw I don't want use my good friend site to sell my stuffs.

well then feel free to pm me as well with details on what you are building, I respect your stance on the sale of your items!

mrbmwx5, please pm me with details as well. Thanks in advance.

Ricky Bobby, r the EvoX-R projectors same diameter as the OEM? Direct bolt-ons? I'd love to see some pics of your project!! Trying to decide wat I want to do with mine...

weren't some Audi A6 or S6 bi-xenon projectors, made by HELLA same bolt-on to the OE pre-facelifts?

I know for a fact that they were, as I did the bi-xenon conversion to my 4.6, but it was several years ago and i think i am getting old here, and don't remember what i had done at the time... But... this info is somewhere on this forum - where else would i get such a crazy idea in the first place??!!!

but those were the lenses, not a bowl...

The Evox-R is a direct swap for the factory projectors. Hella uses the same bolt pattern in most of their projectors.

Thanks... Also, how much rewiring is involved if I would install bi-xenon? And do I have to upgrade to 55W ballast if I go with bi-xenon?

i wired the coil of the bi-xenon solenoid in parallel to the highbeam in the assembly - when the high beam is on, the solenoid comes on too...

execution of this wiring could be tricky - you would need a Y-split - the bottom end of Y to go to car connector, one arm of Y to go to solenoid and the other arm to go to high beam... you would need either assemble this Y using correct connectors or, if somebody makes those specific Y-connectors, just buy them...

hey man, no pics yet as I'm still acquiring all parts, but I can send you some threads to reference on HIDPlanet, but X5SND has upgraded his hella projectors, and Miniz guy has also done a retrofit on the same housings I am getting, but he used Hella RS6 Bi-Xenon projectors instead of the EvoX-R I am using.

The EvoX-R, and the RS6 Bi-Xenon, and the Hella E55 projector are all the same sizing, bolt pattern, etc as our stock E39 low beam projector, so yes, they are a direct drop in, same mounting points and all. The EvoX-R are replica projectors but they are great quality, come with a clear lens (for sharper and more colorful output), and a nice warranty from theretrofitsource.com. The RS6 projectors can probably be had for half the price if you wanted a set, those will not come with a clear lens or chromed bowl however.

No re-wiring or altering of factory wiring if you go bi-xenon, the EvoX-R and RS6 projector just have power and ground for the bi-xenon solenoid that need to be tapped into the high beam wiring. If you are on TRS website, they actually sell the "high beam splitters" as they are called, for 10 bucks. Then you literally plug one end into the projector solenoid, one end into your stock high beam bulb, and the other end into the high beam plug from the car, so when you flick your stalk for high beam, not only will the high beam bulb go on but that power will trigger the solenoid and open up the bi-xenon shield, so you will effectively have "dual high beams", with no modification.


As long as your stock ballasts are in good shape, I would re-use them (I am doing so with mine), 35w ballasts are plenty for the output you get out of the projectors. In my extremely humble opinion, 55w ballasts are overkill, and not only create more heat and shorten bulb life, but they are unnecessary if you are running 4300k or 5000k bulbs. I see 55w ballasts used a lot in 6000k applications, trying to squeeze extra lumens out of higher kelvin bulbs in order to get past the shortcomings of the 6000k output. Also, you need to get bulbs that are meant to be powered by 55w ballasts, usually those bulbs have fatter capsules with more salts in them.

So in short, stick with your 35w ballasts if they power up fine, get yourself a nice pair of projectors and high beam splitters, do your research on other guys who have done retrofits and have a fun weekend upgrading your lighting output. One thing that is a must though? Buy yourself a new set of D2S bulbs, after almost 10 years your light output is about half of what it was when the bulbs were new. That is a must in order to appreciate a new projector (or just to appreciate the light output you had when the car was new!)


hope that helps on your quest,
