You miss the point WA, HIDs are not illegal to be used if they are used in HID equipped headlights, or properly use. But they are illegal to be used in headlights that are not designed to be used for HIDs, like halogen headlights. This topic has been covered so many times already in other forums like HIDPLANET.COM. Halogen headlight reflectors are designed to scatter a lot of light because halogen is weak. But when you put HID in halogen headlights and HIDs are much much stronger than standard halogen, guess what will happen? The result is a ton of glares with no cut off. That is why most HID equipped headlights come with either projectors or the HID reflectors with sharp cut off to limit where the light can go. The cut offs usually look like this ___/---- ___/----. It limits the light from going beyond the horizontal cut off line and left side for incoming traffic. Any how the hell my advice telling him to do retrofit is a fucking ricer comment? You are an ignorant! And why do you think so many people nowaday do retrofit even tho retrofit costs them 5 or 6 times more than just a regular HID kit into stock headlight (~$600 vs $150)?
