Ive been thinking alot about trading my old outdated looking 2 piece headlights for a one piece for the looks and benefits of lighting. I was looking at these (1996-1999 AUDI A4 S4 B5 DRL R8 LED PROJECTOR HEADLIGHTS LAMP BLACK 1997 1998 4DR | eBay) But i have heard some of the headlights you get off ebay are crap. If there are better ones let me know and i definitely want the led in them like the new audi's do. What else would i need? Like a new wiring harness? And is the drilling alot because its my first car and it scare me to death having to drill my car...

 

This topic, just like all of the other threads you've started this week, has been covered many many times. There's a huge amount of information on this forum if you take the time to look for it. If you're retrofitting HID's, you may or may not need to drill holes in the housings for the ballast wiring. Either way, you'll definitely need to trim the fenders. Check this out:
