I bought this set of LED lights to replace my camper tail lights. These are really made for boat trailers, open car trailers, etc, not campers. The mounting design is for bolt heads to clip into retainers on the back side of the housing, then you need access on the end of the bolts for the nuts. I managed to modify the mounting so I could replace the lights on my camper by using the old screws and carefully positioning new holes in the back of the housing to screw into the camper. Also the plate bracket provided will not work on a camper.The waterproof part of this tail light is the internal LED assembly. It is a completely sealed and separate part that screws into the back of the housing. The lense that screws into the black housing is not really waterproof as there is no gasket between the lense and the housing, not that there needs to be since its the LED assembly that is waterproof.The LED lights are very bright and that is the purpose of why I bought them: to increase the visibility of the tail lights, and for that that they deliver.
