I'm trying to decide to go with De Auto LED D3S LED's which are a bit brighter then the stock bulbs, also see how much work is needed to do so.

The bi-xenon headlights DO NOT USE BULBS. They are xenon HID capsules, often mis-called bulbs, and they are powered by something like 30,000 volts from a special ballast assembly. So you've got to disconnect all that and rewire with an adequate 12-volt supply and new wiring, and there's a good chance you'll offend the CAN Bus controller system and need some reprogramming.
Also, an HID capsule mades a fairly broad arc of glowing plasma. That arc is very differently shaped from a light bulb filament, and they both are very differently shaped from an LED emitter or emitter array. The entire reflector and lens assembly is designed to focus the light from an HIS plasma stream--not from a filament or LED assembly.
So while you CAN do a kludge job on this, the light pattern will never be correct and you'll probably **** off other drivers and the occasional cop with glaring headlights, if they are bright. Or, just spend a lot of effort disappointing yourself if they are not.
Short version: If you feel lucky, go to Vegas. Most of 'em will still give you free drinks while you're gambling.

Good information, that's what I was looking for. Their website didn't say what was required from switching from the HID Capsules to LED's

Anyone try any new LEDs for replacing an HID bulbs/ capsule? .. I have D2S's in an 2002 audi.. and found these LEDs that look to be a fit, and
have supposedly built in Canbus wiring etc. so they say.. wondering if anyone has tried these.. They seem to be the only set I can find that will
work in the head light housing.. with the bracket as it is..
