It seems that there is some confusion between the different headlights installed on the A4 B7 so here is a little guide that should answer most of the questions:

OEM Bi-Xenon

http://i31.photobucket.com/albums/c395/fly300kts/Headlight%20Comprehension%20Guide/IMG_7353Large.jpg

YELLOW ARROW: Bi-Xenon - Bulb Type = D1S
GREEN ARROW: Turn Signal - Bulb Type = 1156 (12V 21W)
BLACK ARROW: DRL (Day Time Runing Light): Bulb Type = 1156 (12V 21W)
RED ARROW: City Light - Bulb type = 158,168,194 (12V 5W)




WHY BI-XENON?

The headlight use the same bulb for Low & High beam. Here is how it works:

This is a picture of the beam housing removed from the headlight. You can see the D1S bulb installed. Also note the grey metal plate in the front.

Same housing, side view: you can see that the grey flap is in contact with the housing: This is the LOW BEAM POSITION

When you select High Beam, via an electro magnet, the grey flap tilts forward: This is the HIGH BEAM POSITION

HALOGEN

YELLOW ARROW: Low Beam - Bulb Type = H7 (12V 55W)
BLUE ARROW: High Beam - Bulb Type = H7 (12V 55W)
RED ARROW: City Light - Bulb type = 158,168,194 (12V 5W)
GREEN ARROW: Turn Signal - Bulb Type = 1156 (12V 21W)

I think I covered everything and now it makes sense for everyone
Let me know if any question

PERFECT!!

BLACK ARROW: DRL (Day Time Runing Light): Bulb Type = 1156 (12V 21W)

Now i know what type of bulb specifications to get when getting a white color without throwing an error!!!

Well, here is the catch in your case:
I assume that you will be looking for LED but you will not find an LED replacement with a 21W draw. They will need to have a resistor built in and I have not seen, yet, these in 1156 socket type

Forget the LED then I'll just stick with the regular bulb and find a white one :)

hmm, I thought there was a oem Halogen projector equipped with b7's as well. So if its an oem projector, its always bi-xenon?

It's too bad only a handful of people will read this before asking whether they have xenon headlights or not.

Great write-up nonetheless.

Awesome post Phil! My city lights are out for delivery now and should be here shortly. I was planning on just going to the garage and fiddling with the different bulbs but I can already tell this post saved me a lot of time.

Crossing fingers on no code .....
