I need to add some auxillery lights to the rear of my 2500 so I can what I'm doing back there when hooking the trailer up in the dark. It will also benefit me when backing at night in an unlit lot. Any ideas out there on you went about wiring things up?

On my old Ford I had a pair of NAPA tractor lights mounted under the rear bumper. They use a 4" sealed beam in a rubber houseing. I wired them to my backup light switch with relays.

Here's what I did on the back of my 3500..I had a piece of flat stock welded to the underside of the trailer hitch and mounted two lights on it. Originally I had a set of cheap Cabela's brand halogen back up lights. I just replaced them with Rigid Industries SRM series flood lights. They are absolutely awesome. Aluminum housing, weatherpac connectors, very well made. Made in America as well. I wired them right into the back of the trailer wiring plug so they come on with the reverse lights.

I usually add auxillary reverse lights to my plow trucks. I generally use the rubber housing tractor light with sealed beam bulbs. I like to wire mine with a relay. I usually run my battery feed for the relay through a switch in the cab and out to the relay. I tap into the reverse light wiring for my switched relay power. That way any time the switch in the cab is on and your in reverse the lights illuminate. Also keeps you from forgetting and leaving them on when your driving down the road. I also like to mount my relay behind one tail light or the other to simplify wiring. That way you only have to run the wire from the cab switch back to the relay. Everything else is in the back.
