Last year, I bought a trailer which had generic incandescent lights installed on the wheel fenders. Previous owner had recently re-done the lighting and wiring, and I'm not sure how close this setup mimics the original. The lights are solid mounted on the fender, and I know the originals were on the fender too. Not sure if they were isolated somehow. They do not hang off the side - fender would contact anything first. Thanks for your replies.
