I've bought other wiring harness kits and what I liked about this one is that it was LED so no need to mess with bulbs. In fact, the body of the lamp is closed - there are no screws or, apparently, no way to open it. So I assume that if the bulbs burn out, I'll have to replace the lamp housing. It could be pain. But LED lamps usually last "forever". So I might have to post again later if this turns out to be a problem. My 6ft trailer didn't need a 25ft seat belt, so I wrapped about 18" around the brake light post (for future use), cut off the rest and threw it away. for an old girl like me
