Troubleshooting Your Trailer Lights: How to Get Them Working Again



Do you have a trailer that isn't lighting up? Perhaps its lights aren't functioning or are on the blink. It's possible to fix this issue yourself, but first, let's look at what trailer lights are and how they work.

Trailer lights help drivers of vehicles with trailers to travel safely both day and night. They allow drivers to signal when slowing down, turning, changing lanes, or making any other movement on the road. At night, these lights make it easier for others to see and detect the presence of the trailer.

Common Causes of Trailer Light Problems



There are several potential causes of trailer light problems. The most common are electrical failure, broken wiring, corroded sockets, or blown bulbs. In some cases, the lights may be left on and the battery may be completely drained.

How to Troubleshoot Your Trailer Lights



If your trailer lights are not working, there are a few steps you can take to troubleshoot and potentially fix the problem yourself.

• Start by checking the trailer’s electrical connection. If the connection is loose, securely reconnect it.

• Inspect the wires and connectors. Look for signs of wear and tear, corrosion, loose connections, or fraying.

• Check the fuse box and replace any blown fuses.

• Check the bulbs. Make sure they are not broken. If they are, replace them.

• After checking all of the above, make sure the lights are correctly wired. If the wiring is incorrect, rewire them correctly.

• Turn on the lights and check if they are functioning correctly.
