Selecting The Best LED Trailer Lights, Wiring, and Adapters

4-Way vs. 7-Way Trailer Lights Wiring

If you are not an electrician, like most of us, wiring your trailer lights may not be intuitive but it's also not impossible to learn. Installing a trailer light kit or fixing a segment of broken wire requires more than a few sentences of instructions. Before you jump into the installation process, it is important to figure out whether or not your trailer utilizes a 4-way or 7-way wiring harness. Typically, you will find 4-way wiring harnesses on boat and utility trailers while you will find 7-way wiring harnesses on standard trailers, trucks, and RVs. The easiest way to tell which wiring harness your trailer requires is to find the trailer end or vehicle end connection of your trailer lighting system. You will either see 4 or 7 connection pins in addition to 4 or 7 wires extending from the trailer or vehicle end connection. Both 4-way and 7-way wiring harnesses provide the required power for running lights, turn signals, brake lights, and ground wire. The 7-way harness has three additional pins for a 12V hot lead, electric brakes, and reverse lights.

When Are Lights Required to be Installed on a Trailer?

All trailers are required by federal safety standards and DOT regulations to have stop lights, tail lights, turn signals, and reflectors. If your trailer is wider than 80" and longer than 30', additional trailer lighting and reflectors will be required.

How to Test Trailer Lights

When your trailer lights are not working properly, there are a variety of things that could be causing the issue. Here are some items to check when testing your trailer lights:

  1. Check the Bulbs
    The obvious culprit would be broken light bulbs. Test the bulbs to make sure they are not broken or burnt out.
  2. Inspect the Wiring System
    A quick physical inspection of the wiring system for your trailer lights may reveal some damage that could be causing the issue. If several wires are contacting each other or one wire has accidentally been severed, this can be the cause of your problem. You should also check the terminals and fuses for signs of corrosion and other damage.
  3. Use a Trailer Wiring Tester
    If you have one on hand, a trailer wiring tester can help you identify the issue. The device should respond to each individual system to indicate whether or not it is receiving an electrical current.
