Trailer Lighting Kit Buyer's Guide
Wondering how a trailer light works? Let's break it down step-by-step.
Remember, all trailers have a plug that is connected to the tow vehicle’s lighting circuitry, with a corresponding connector on the trailer, a wiring harness, and stop, tail, turn and side marker lights around it.
Trailers less than 80 inches wide
In this instance, your trailer will need tail lights, stop lights, turn signals, side marker lights, and side and rear reflectors on each side. Legal requirements state you will also require a license plate light. Trailers wider than that might need more side marker lights and side reflectors.
Trailers more than 80 inches wide
Trailers that exceed 80 inches need more lighting to illuminate them at night. You will need three red identification lights situated on the rear of the trailer. You will also need clearance lights, which should be placed near the trailer's fenders.
LED lights versus traditional incandescent lights
LED trailer lights are the preferred option due to their increased longevity. LED lights provide 100,000 hours of light, compared to incandescent lights, which only last for 3000 hours.
LED lights are encased in a polycarbonate lens, decreasing their ability to rust or corrode. They are immune to thermal shock, as they release minimal amounts of heat, and they switch on instantly. They also tend not to protrude from your trailer, making them less likely to be damaged during an accident.
Steps On How To Install Your Trailer Lighting Kit
First, you will need: four wire trailer light harness, lights, wire cutters, wire strippers, split loop poly casing, electrical tape, soldering iron, adhesive filled shrink tube, drill, center drill and drill bits, center punch, hammer, paint marker, retaining loops and cable ties.
Draw a diagram of your new wiring on a piece of paper. Use that as a map during your rewiring process. Pull out all the old wiring before you get started. You can unbolt them from the trailer's frame. Now, pull the wiring out through the front of the trailer commonly referred to as the tongue.
Place the wiring throughout the frame of the trailer. Remember that the yellow and brown wires should connect to the driver's side and green and brown goes to the passenger's side. Now, ensure that you have an equal amount of wiring on either side of the trailer. The white wire remains close to the trailer's fender. Leave enough wiring over so you can plug it into your SUV or motorhome.
Now, expose the wiring of the white ground wire by stripping it. Take out the existing bolt and wrap the exposed copper wiring around it and put it back in place. Make use of a ring terminal and attach the wire to the bolt. Safely put away all excess wiring before moving on.
Strip the end of the white ground wire. Then, remove the ground bolt or existing coupler bolt previously used for the old ground wire. Wrap the exposed copper wiring around the bolt and put it back.
Use your bolts to mount new trailer marker lights. Bolt the lights onto the trailer. Now splice in the marker light wires to trailer wiring. Correctly connect all the wiring.
Fasten the wiring to the trailer from front to back. You need to ensure that the wiring is securely attached to the trailer.
Now it's time to install the tail light, which must correspond with both the driver and passenger's sides. Once you've positioned the light properly, clip the wire, then insert it into the correct connection points. You must ensure that the yellow and brown wires connect to the driver's side and green and brown links to the passenger's side. Now attach the tail lights onto the trailer frame.
The last step is to test that your new trailer lights work. Connect the trailer to your car to ascertain whether the lighting functions work in tandem. Make use of an electrical tester to troubleshoot any issues with your new wiring harness. Triple check that the brake lights, running lights, right turn signal, and left turn signal are working properly before you take to the road.

What are the functions of the three wires on the LED light?
A LED light acts like a multi-functional light. The three wires are white, black, and red and they all perform different functions. The black and red are the positives and the white wire functions as a ground.
You can use a 9v battery to test the polarity of your LED light. Press the wire you think is the negative side onto the negative side of the battery. Hold one of the other wires against the positive side. This should do the trick.
Buying the best trailer lighting kit will require you to conduct good research and plan wisely. You must follow the trailer installation guidelines. Make doubly sure that you work within the framework set out by the United States Transport Department.
