I just had two double halogen lights installed, mounted to the bottom of the bumper. Wired to the pin...mine was a centre pin power to the Dodge dually. I had to have a relay installed so the lights run off of the trailer battery. We then put a switch inside the trailer so the lights work both in reverse and can be manually turned on from inside. Yes the dual halogens are bright. But when I need to back in at night I can use the back up camera and it shows just as it does in the day time.
Good luck with your set up,
Respectfully,
