I have an old stock trailer that I just replaced all the wiring from the plug to the lights. This is a 4 prong plug and there are only 2 lights on the back end. I ran the wires and checked that they were working correctly at the back end before I attached the lights. The lights I bought were LED 3 wire lights. They have one wire for the tail light, one for the stop/turn, and one for the ground. The ground one had a little crimped on loop in the end of the wire so I could just screw it into the trailer, but I didn't. I connected it to the ground wire coming from the 4 prong plug. The others I connected to their correct wires.
Now for the problem.
When I have my lights on, the blinker/brake light does not work. If I turn off my lights the blinker/tail light does work. The lights won't let me have both a tail light and a blinker/stop light.
I looked it up on the internet and one thing it said is possibly not enough grounding. I connected it directly to the ground wire from the plug. Is that enough? Should I have screwed it into the frame?
Could I just have faulty lights? Both of them act the exact same way.
