Right LED tail light staying on
Here's an unusual problem that has cropped up in the past week. Can't get my right LED tail light to shut off. The trailer is not plugged into my truck. The only way I can get it off is to disconnect ...

Well I believe I found the problem. As some of you have suggested the problem is in the seven way plug. Checked the terminals, the right light was getting 4 volts. Sprayed the plug with DeOxIt electrical contact cleaner. Rear light got very dim, voltage went down to 2 volts. Rapped the plug a bunch of times against the frame, light went out, voltage went to zero. This plug is a molded plug onto the wire so that's why I couldn't take it apart. I suspect moisture get into it one way or another creating corrosion. We had a tough winter here this past year and it pretty much stayed below freezing for about 8 weeks. When our thaw happened last week is when the light came on. I'll replace the plug in a week or two just for the heck of it and cut the old one apart to see if I could find what problem was. A big thank you to everyone for taking the time to give me your opinion!
