Last week I installed my LED taillights. Everything was fine. Saturday went on a 290-mile ride. Got home and started to clean the trike. I noticed the taillights on the right side was loose. I took the LED off. There's a large screw at the top to hold it on the fender. I tried to tighten the screw, but it wouldn't tighten up. I ended up taking the trike to the dealership. They tried to tighten it, with no luck. In the end, they said it was better than it was. What? They said it might be stripped out. I can take the light and move it right to left. Still loose. Does anyone have a Diagram of the taillight of how it supposed to be mounted to the fender? The left taillight is fine. Thanks.
