By law you can’t travel anywhere in the US while towing a trailer unless your trailer is set up with the proper brake lights and turn signals. This is because without these lights, it becomes a hazard to your fellow motorists on the road. However, lights in vehicles can burn out rather quickly, thus it’s important that you should routinely inspect your trusty LED trailer lights and its wirings and connections.
How It Works
Before you can figure out how to inspect, maintain, and troubleshoot your trailer lights, you should first know how they work. Usually, trailers will have up to three circuits connected to your truck—one for the taillights, and two for each brake light. These lights behind your trailer play a significant role in keeping you safe while on the road wherein they serve as warnings or alert signals to other drivers around you.
The LED Difference
Today, LED lighting is the staple among trailers, mainly for the various advantages it has over conventional options. For one, LED is brighter, which means that people will be able to see your brake lights clearly, especially in the day. Moreover, they also illuminate faster, allowing them to respond to your turning or braking more quickly.
Inspections and Troubleshooting
Dan Armitage writes in BoatsU.S. about how you can perform basic inspection and troubleshooting on your trailer lights:
“The most important part of troubleshooting a trailer lighting issue is giving the rig a simple, but thorough, visual inspection. That involves checking the vehicle-to-trailer connection and all ground connections, which are usually made with a white wire, to make sure they are clean and have direct, metal-to-metal contact with the trailer. With all of the grounds checked, look to see that the wiring on the trailer is physically intact, checking for any obvious breaks or nicks in the wiring, and repair as needed.”
During your inspection, be on the lookout for signs that you might need a new connection—but there are steps you can take to ensure that this won’t happen in the first place. For one, don’t connect the trailer hitch to your truck’s tow ball, as this could provide false ground for the trailer. In fact the jack-and-plug connection should be the only connection to the trailer.
If your trailer lights have burned out or its wirings have gone faulty, you should have them replaced right away before your next vacation or hauling trip. Look into reputable dealers like Global Parts Inc. for trusty and reliable LED marker lights or brake lights.
