my stock lights are fading and i wanted to get xenons to replace it like the ones the 2001 s4 has. just a couple questions, what size am i looking for, around how much would it cost, do i buy a kit or just the bulbs, and what brightness does the s4 have, or whats a good brightness to have?

any questions or comments will be greatly appreciated.
thanks.
