All 4 headlights, 2 dim 2 bright, use H7 bulbs. The last person to work on your car must have dropped it ( the clip) and didn't care. When I got my car the passenger headlights were not aimed together like they should have been, I think that it had been in a small fender bender because I now have the SRT-6 nose and it is not a SRT-6. I bought a used assembly on on Ebay and replaced the old one and it is fine now. Once you get the hang of it the bulbs arn't really that hard to replace. The headlights if working properly and aimed right are one of best for night driving I've ever had. I don't think satan designed the headlights ar anything else on the car but I think the guy that did design some things knew him How about that cupholder and that secondary air injection system!
