My 2015
Scamp came with tailights that included the clear lens window and bulb for back up
lights, but my 7 pin was not wired to power them. I added a switch in the
Scamp so that I could open the door, reach in, flip the switch, and have back up
lights powered by the trailer's
battery. But it was really more of a security thing than for
light when backing up the trailer.. I could illuminate the area behind the camper when I was inside and heard strange noises. But eventually I repurposed the hole the switch was mounted in to something more useful since I never used the backup
lights for backing up, nor for checking what creatures were making noise behind the camper while I tried to sleep.
