Another quick add-on: I think all of the Xenon lights I've seen are projector- BMW, Audi, Porsche and Lexus definitely. Don't know about M-B (most likely) and Acura. OT: On the Audis, the Xenons are projector lights, but not all projector lights are Xenon. My 99.5 A4 Avant has the projector lights, but not Xenon (unfortunately). TM 99.5 A4 Avant 1.8TQMS
