don't ground thru the trailer frame. run a dedicated ground wire to each light. i gave up. i now run the magnetic lights from Harbor Freight. i ran a 4 set wire from the tongue to the back of trailer and put a plug on both ends. i unplug the lights and put em in the tool box to launch and put em back on when i take the boat out of the water. haven't had a problem yet.
