You do not need to go and spend hundreds on a "projector" retrofit...
Everyone on this site OBSESSES with the fact that HID systems MUST be projector. This is wrong.
There ARE cars that do use HID Reflector systems, although technically they are made for HID light output.

Namely:
Acura TL (older models, 99-00 etc)
Cadillac Escalade
Infiniti QX4
Etc.

Why not compare the light output of one of the cars listed with the light output from a DIY reflector-HID system and post the images?

Bottom line is you do not need to retrofit HID projectors.
