I'm selling a set of dual halo projector headlights as I've bought them off ebay and saw as I took them into the Audi dealership to have them installed, that they didn't fit the vehicle and required a decent amount of modification to the front end. They fit the years 99-01 for the b5 a4 since those years have the one piece headlights. I'm asking 140 bucks or best offer. Local pick-up only, so send a message if interested, or my AOL Instant Messenger screenname is AccordLX160. Here is a pic of what the headlights look like.

 

Those don't require a ton of modification. You'll need to trim part of the fender. I did it. Here's a picture and a DIY:
