I have a 2002 C230 coupe. it doesn't have zenon headlight and it's not an option in 2002. but in 2003, they have option on it. I just wonder if i can order the 2003 factory HID with housing and put it on my car? will it work? does anyone know about it? or do i need to set the computer or anything to be able to install it to make it work? please tell me
