I just finished installing my M&R 23" Pro Lights. It went like expected, a major pain in the ass! Getting the side panel clips off, to access the three bolts underneath each of them, was a nightmare for me. Additionally, I broke the plastic push pin holder on the drivers side (that was the first one I pulled). It is taped down for now while I look for the part or figure out a way to rig it. Several of the push pins also didn't want to go back in correctly. I'm going to order new push pins. Now that I'm done I like the way they look. If I had to do it over I would have taken it to someone or skipped installing them altogether.
Tomorrow I'm doing the rear backup lights. Should be a lot easier although M&R didn't label the mounting brackets. I'll figure it out by watching the video.
