I seem to be typing a lot this morning. Me and my big fingers! Be careful in what you buy. I ordered a set of lights. Thinking I was going to get two clear back-up lights. What I got were a set of R32 lights one side is clear the other is for the rear fog light. (And Red) I am not going to go throught the hassle to rewire & reprogram my system. I'm just going to have one red lense and one clear. My state has a yearly inspection (PA). If they give me any hassle I'll just chance the one stock light back in for the inspection. As far as difficult. Inner lights no problem, remove cover on hatch, turn out bulb and socket, you have to manuver the wrench to turn nuts. The outer lights, I found taking the trim from around the hatch opening the easiest to get to the side panels. It just pulls (Push/LIfts) off, I didn't remove the adjusters from the stock lights, I just left them in, seemed to work out alright. You might have to shim new light if they don't fit flush. I didn't. By the way I have a Candy White with blacked out lights. I think it looks fine, and I guess that all that counts.
