Thanks guys, that actually does clear up a lot of things. I'm confused when you go to the stores and they have things like HID H4 then they have something thats described as 'Like HID but you don't need to convert'. Is that the tinted glass your talking about?

Man, that really sucks, how come we can convert them on the old cars? Isn't it safer to have HID than the normal Halogen? Bastards!
