On my toy hauler, there is a wire in the 7 pin connection and wiring harness on the trailer for backup lights. Mine wasn't being used, but was there going to the back of the trailer. I used my overhead loading lights in back by tapping into the switch and added a relay so that the lights come on when I put the truck in reverse. I'm probably going to add lights down low just because.
