I just finished my LED conversion. Turn signals (white/amber switchback for the front), reverse lights, license plate, interior; all white. Pictures coming soon.
I'm think about doing something like the Audi LED's for the front. Just not sure where I would put it. If anyone has an opinion, I'd love to hear it.
