Third brake light repair
I failed inspection because my third brake light was out. I changed the bulb and it worked for a few days and then went out again. I took a multi-meter and tested the bulb and it was still good, so I knew the problem was with the fixture. I finally figured out how to remove the fixture and I found that one of the contacts was burned and pitted. As a temporary fix to pass inspection I cleaned the contact and bent it so it would make better contact with the base plate. I had some time today so I took everything apart and did a better job with the repair. This time I removed the bad contact and put a blob of solder on the pitted area and filed it down so that it would make a better cleaner contact with the base plate. The attached photos show some of the steps in the repair process.
Just a note. I never got any lamp out message, so I didn't know it was out until I failed inspection
