After reading al the threads on HID upgrades i came to the conclusion that the only 2 bulbs that will fit a 2003 alfa 2.0 jts are the H7C and H7RC is there anyone that tried one of these bulbs in a 156 jts yet?
I haven't yet but I'm considering the H7RC as they are the only HID bulb to fit considering the lamp shield, and they have the blocking strip at the base of the bulb which restricts certain angled beams, making them ideal for cars that are not fitted with projector lens(which is a legal requirement).
Beware though, I still don't think they're legal to use without projector lens, even with the blocking strip. I think they just make it less obvious that you're using HIDs without projector lens.
