4 wire trailer brake lights not working

Four wire trailer brake lights not working can be a mighty nuisance for any driver who’s trying to stay safe on the road. Improperly functioning lights can create serious safety hazards, especially if you’re dealing with large vehicles like trucks or trailers. Fortunately, identifying and fixing 4 wire trailer brake lights not working isn’t as difficult as it may seem.

The first step to addressing the issue is to verify the wiring. If there are four wires connected to the rear brakes on your trailer, it should be easy enough to ensure that the wiring is properly connected. You might need to enlist the help of a professional if you’re not comfortable tackling this yourself. Once the wiring is verified, you can move onto other possible causes of the problem.

The next step is to evaluate the power sources for the brake lights. Check to make sure that the bulbs are properly installed and that the power sources are functioning correctly. If the power sources appear to be functioning properly, you may need to replace the bulbs in order to get the lights working again. Finally, inspect the brake switch located near the brake pedal. If the switch is faulty or there is corrosion on the connection terminals, it could be preventing the brake lights from turning on properly. Replacing the switch should remedy this issue.

By taking the time to investigate these potential problems, you can identify and resolve your 4 wire trailer brake lights not working issue. With your brakes back in order, you can enjoy safe and stress-free road trips.
