I have a camper shell on my p'up, so backing up can sometimes be a challenge, especially at night. I want to put more lighting in the back that is connected to a relay that turns them on when I am backing up. Most of the lighting I have found is designed to be mounted on top of the bumper, but if I do that, the tail gate is not going to open. I would like to get 4 round lights, about 2" and mount them in the bumper - drill holes into the bumper and screw them in tight. (I think) this would give me the lighting that I need, keep them out of the way, and provide a great deal of protection for them. Is this a good idea? Giggle only shows me the bolt on lights, or the small ones used as side markers for trailers or big rigs. Can anyone give me some search terms to help me find what I am looking for? (If it is a good idea). I don't think upgrading the white backup light in the cluster to LED would give me the amount of light that I am looking for...or maybe I can do both.
