If you want to have HID for your low and high beams you will absolutly have to use a Bi-xenon projector. It is VERY bad to turn HIDs on and off repeatedly, and you would be doing this everytime another car came along with a dual projector setup.

I don't know of any high-beam specific HID projectors. Also, all you would have to do is remove the shield in the projector for a highbeam setup.(Basicly what what a Bi-xenon projector does when highs are switched on)
PunkAssKidThe1s, there is a good bit of wiring needed to hook up the solenoid on a Bi-xenon, so make sure you do your homework!
