Day 13, my first actual repair. Left tail light didn't work. Easy access, easy repair. Take out the 6 screws, push gently on the plastic catch on the inside, unplug the connector and you've got the board and bulbs in your hands. The way this is made, many bad or intermittent connections have to occur on these light assemblies. Much riveting, no soldering. I hooked up the board without the lenses and my tail light would come on by moving the socket. Bad, connection to the shell of the bulb. The solution, solder it. Clean off a little spot on each side of the socket shell and strip, (sand it, scrape it, whatever) and solder it to the strip. When you solder, use soldering paste, no acid flux or core. I don't really want a big argument about using paste, I'm older than you and I've been doing it longer than you and I don't want to explain the why of it at this time, maybe later. Thanks.
