Travel trailers are great lightweight campers that can give you a little luxury while out in the great outdoors. However, like a full-sized camper or RV, they can be difficult to tow. This is especially true when you are backing them up. Having the right lighting at night can make all the difference between a collision and safety.
Do travel trailers have back-up or reverse lights? Yes, many higher end trailers (like toy hauler, cargo, etc) have backup lights built in. You probably have the reverse light circuit wired in if your tow vehicle (with factory tow package) has a seven pin connector.
If you are towing a massive travel trailer in the middle of the night, it is necessary that people behind you can see you. The use of back up lights is necessary, and they are easy to install. If your trailer does not come with back-up lights you need to read on to find out how to install the trailer reverse lights.
Do Travel Trailers Have Back-Up or Reverse Lights?
Since the Department of Motor Vehicles does not require travel trailers to have back up lights, most manufacturers do not install them on the stock models. However, many higher end trailers (like toy hauler, cargo, etc) have backup lights built in. Even though it is a good idea to have back up lights on your travel trailer, you won’t see them on stock models of travel trailers because there is no legal obligation for manufacturers to add them or owners to use them.
Should You Install Reverse Lights on Your Travel Trailer?
Backing up a travel trailer at night is hard enough. Letting other drivers know you are in reverse can help you to stay out of accidents. Therefore, it is recommended that you install reverse lights on your travel trailer.
How to Install Back-Up Lights on Your Travel Trailer
You can install the lights on a trailer for backing up with a seven-pin wiring configuration and a new set of lights. It does not matter whether you install the travel trailer lights yourself or having an auto shop install them, back up lights are possible to install on virtually any travel trailer.
Connecting and towing a travel trailer with back-up lights to your vehicle is relatively easy. If you are willing to buy new parts for the connection and the lights, you can install your back-up lights for the travel trailer.

Connecting the Wiring to Your Vehicle
Connecting the wiring to your vehicle and your travel trailer is relatively simple. However, you will need to do some work to get the back-up lights installed. Before you start, make sure you have the seven-pin wiring system with the central pin for reverse lights.
Follow the steps below to install the wiring to the travel trailer and your vehicle:
- Using a plastic wedge tool for cabin panels in your car, prop open the back fuse set. This is usually located somewhere near the tailgate of a truck or in the trunk of cars, SUVs, or vans.
- The seven-pin wiring set can be plugged into this fuse box and should have about four to six feet of wires coming from the plug dangling out.
- Wrap the wires and tie them with a wire holder to the length you need to reach the tongue of the trailer.
- Measure the length of the wire you need to reach the back end of the travel trailer to the tongue where the lights will connect to the vehicle wiring.
- The gauge of the wire you use for the back-up lights can be either sixteen- or fourteen-gauge. Some of the best wire choices for this installation are:
- 16 AWG (True American Wire Ga) CCA Copper Clad Aluminum Primary Wire: The copper-clad wire from True American Wire is made from 42 strands of copper and aluminum metals. The wiring comes in black or red and for twenty-five-foot rolls, perfect for reaching the back end of the trailer.
- Grand General 55244 Red 100′ 14-Gauge Primary Wire: The red fourteen-gauge wire that you receive in this bundle is called the grand general because you get one hundred feet of wire. The outer PVC coating on the wire is also water, chemical, and corrosion resistant.
- Drill the holes where the lights will be mounted on the tail end of the travel trailer. Make sure that the lights will be mounted evenly and as far to the sides of the vehicle as possible.
- When you feed the wire from the holes, you can either zip tie the wires under the carriage of the trailer, or drill holes through the undercarriage to make a straight line for the wire to feed through.
Connecting New Lights to your Travel Trailer
Depending on the lights that you choose to install on the tail end of your travel trailer, the drill holes you make might need to be larger than you initially drilled them for the wiring.
Follow these steps to mount your new lights to your travel trailer:
- The lights you purchased most likely have rubber grommets that should be able to fit into the drilled holes at the tail end of the trailer. These grommets should fit snugly and keep the lights water-resistant.
- Drill out the hole to the size you need to fit the grommet.
- Place the light on the hole and attach the wiring before you attach it to the seven-pin wiring on the vehicle.
- Attach the lights with the bolts or screws that come with it. You may want to drill pilot holes.
Connecting the Wiring
Once the back-up lights are mounted and connected to the fourteen- or sixteen-gauge primary wire that is thread through the body or undercarriage of the trailer, you are ready to hook up the trailer lights to the vehicle.
Follow these steps:
- The trailer will have other wires from the brake lights and possibly even turning signals. The back-up lights should be attached to this bundle for safekeeping. The bundle is usually wrapped in the protective plastic sheathing.
- Each of these wires can be plugged into their corresponding pins on the seven-pin wire plug from the vehicle.
- Make sure that the wires from the back-up lights are plugged into the central pin of the seven-pin wire socket.
