Have you guys seen the redesigned Audi A4? I love the headlight design and I think it'll look great if adapted into the Scion tC. Expensive? I bet it will be, lol!

A lot of cars now have LED headlights so you will want to find some high powered LEDs in order to do that. Phillips seems to be the best for that.

Actually very few PRODUCTION cars other than Audi A4, S6, R8, and S8 have LED headlights. Only other car that comes to mind is the Lexus LS.
