OK....I see a lot of people putting in Audi TT projectors, etc. then they say their color still isnt like TT. The projector doesnt have anything to do with the color right???
Also...some Lexus have OEM HID....does it hook up the same as aftermarket HID does? I mean why couldnt I put in any model HID as long as the little bulb fits into my headlight?

 

you can. but some cars take additional splicing of wires. i believe bmw is the only car that you can take out and plug in and go. besides buying a bulb
