Question:
I have a 8ft trailor that I would like to put a back up light for backing up at night, my trailor has a 4 flat harness and where do I connect the wires from the light to or will I need special wiring for this. Thank you

The Bully Bumper Mount Backup Light # PL-807 can be used for your application.
To wire the light to come on when you put the vehicle in reverse to back up the trailer, install a 5-Way wiring harness on the trailer using # HM47910. The extra wire could then be attached to the power wire on the light.
You would then need a 5-Way adapter on the vehicle side, # 20036. The extra blue wire will attach to the reverse light wire on the vehicle to power on the light when you put the vehicle in reverse. I have included a video showing a typical installation for you.
