Adding reverse lights

AAnt...I'm sure your fellow campers thought those 55W Halogens were great when you came rolling in the night too....

A friend of mine has 2 Halogens, and he turns them on seperately.They are angled to be less intrusive to fellow campers....2 out the side seems to be overkill.

Thanks everyone for your suggestions. I will check the center pin this weekend. I like the idea of adding lights in front of the trailers wheels also and will probably do that as well. Travel on.

Use the relay that comes with most driving lights and power the lights from the camper battery, but switched by the pickup reverse lights though the pigtail. I had four 55 watt halagon backup lights on my old rig, two out the back and two out the side. Great for rolling in at night. Also consider high lumen LED which would eliminate the need for the relays.

As others have said the center pin of your plug should be for back up lights. When I mounted lights on the back of my 5th I wired them with a relay so the power is taken from the trailer battery. My 5th was wired up to the pin box so I had to run a wire from there back. Another idea I had was to mount a light on each side facing back just in front of the wheels. I have these on a switch so if I have to maneuver back and forth in the dark I can keep an eye on how the trailer is doing even when the backup lights are off.

My suggestion is to use a manual switch to turn them on when they're needed. At the same time set up your back up lights on your truck with a manual shut OFF switch so you can actually USE the lights on the trailer. Back up lights reflecting off of the front of the trailer will KILL your night vision making the trailer back up lights next to useless. You'll be surprised how much difference it makes to get rid of the trucks lights when backing.

I have added reverse light to two trailers. Mounted the lights on the back bumper. One wire to ground the other to the center conductor
of the cable. Both of my trucks used the center conductor as reverse lights. You can check your truck with a meter. Center pin should go to +12 when truck is in reverse...

mine light up the entire campsite when I back up

Our present trailer came with back-up lights standard... they go on when I put the tow vehicle in reverse.
Honestly, I don't think they help me maneuver into a site at all. I can't really even see them. Maybe they are good for warning someone behind me that I am backing up, but that's about it.
If it's dark or I can see what is behind me, my wife pulls spotter duty.

I bought a $20 set of round driving lights for my fiver. Wire the ground to the trailer frame and take a wire from the light positive wire up to the electrical junction box near the pinbox. Inside the pinbox, there will PROBABLY be a single wire with a wire nut on it coming from the main cable which plugs into the truck. This one will provide power to your new backup lights when you put the truck in reverse. You might possibly have to put a fuse in the truck to make it work. Start by checking that you have power to the backup light terminal on the truck plug when the truck is in reverse. If you have power there, plug in the trailer plug and check for power on that single wire with the wirenut.

I just bought some back up lights at Meijers for my previous TT. For about $20 came with lights, wire. I then ran the wire up to the pass through, put in a switch, then ran the wire to the battery.

Not extremely convenient, but cheap. Never needed or used them in the years we owned the TT.
