just a quick note, HID is High Intensity Discharge & Halogen lamps have filaments.
I dug the spare Skyline headlamps out and my word they are crude , just a simple reflector and a lens with a plate that acts as a mask to chop the beam, all very Victorian!
I see the Canadian’s are getting into trouble with the local DOT for not having head lamps that comply with regulations. I suppose I should really get up off my ass and make a properly converted right-hand drive to left hand drive HID kit.
The reflector in there sucks and would need to be re-designed to work better with that little arc and the lens is a cheap POS ( I think I know who made it)
Problem is will these penniless skyline owner be prepared to pay for the R+D, hum probably not ? and do I want a pair of $5000 head lamps - er no.
