I needed a quick set of lights to put on a project trailer I was making out of an old camper. These worked out great for the situation. I just needed to get the trailer down the road legally and was not to a point on the project that I was ready to put permanent lights on it. Only worry was the strength of the magnets. on a bouncy trailer I didn't think they were strong enough but if used while towing a car with a suspension they would work out just fine. I plan to keep them in my truck for any cases when my trailer lights don't work and I need something to get me home.

Thought I might get out of rewiring my trailer as the squirrels had destroyed it. I plugged these up and they worked initially. Stuck them to the trailer and took a short, trial ride. When I returned, the left light was totally out, and the left parking/tail 10 amp fuse was blown. Something was also rattling in the left base unit, and three base connecting wires simply fell out of the base. I probably could have disassembled these, rewired and corrected the problems, but at the price I figured why? I returned them. Not a good fuzzy. I ended up getting a 4-wire spool, some connectors, black tape and rewired the entire trailer, all is good now.
