I have a 2000 s4 but i want to know if i can get brighter bulbs....cause the stock ones suck or do i have to go all out and get a whole nother...set up?

Audi bulbs are at the brightest end of the spectrum. I would recommend picking up some Ecode housings. Not only do they look better but the light pattern is 10X better than US housings. They are kinda pricey though.

very good idea man! Are they the ones you can get with the black housings too? they look sweettt

yep!
