Common Causes For Trailer Lights Not To Work

Whether you’re towing a dump trailer, car hauler, or another bumper pull trailer, lights are just as important as a secure hitch and properly inflated tires. They’re essential safety features, keeping you and others on the road safe. Imagine cruising down a busy roadway at night like 53rd Avenue in Bradenton, FL – without working trailer lights, you become invisible to drivers behind you. Not only is this a significant safety hazard, but it can also land you a citation.

So, if your trailer lights are not operating, here are some common causes for them not to work:

Faulty Ground Connections

Grounding issues are a common cause of trailer light problems. A good ground connection is necessary for completing the electrical circuit. Corrosion, grime, or loose ground wires can disrupt the flow of electricity, causing trailer lights not to work.

Fix: Inspect the ground connection points on your trailer and tow vehicle. They are typically located near the trailer hitch and the connector plug. Look for any signs of corrosion or loose connections. Clean the contact points with a wire brush and tighten any loose bolts.

Burned Out Bulbs

Sometimes, the simplest solution is right in front of you. If your trailer lights are flickering or not working, a burned-out bulb might be the reason.

Fix: Replace any faulty bulbs with the right type for your trailer. Bigfoot Trailers use LED light bulbs, which last longer and use less energy.

Blown Fuse

Sometimes, the issue lies hidden within your vehicle’s electrical system. A blown fuse for the trailer lights can stop everything from working.

Fix: Consult your vehicle’s owner’s manual to locate the trailer light fuse box. Replace any blown fuses with ones of the same amperage rating. If replacing the fuse doesn’t solve the problem, your trailer lights may have an electrical issue that requires professional repair or replacement.

Damaged Wiring Harness

Trailers are exposed to weather and various road conditions. So, their lights and wiring are susceptible to debris or wear and tear. A frayed, pinched, or broken wire can disrupt the electrical circuit and cause your lights to go dark.

Fix: Visually inspect the trailer wiring for any signs of damage. If you find damaged wires, it is best to replace the entire wiring harness.

Loose Connectors

The connection between your trailer and tow vehicle bears the brunt of the elements. Over time, the plug and socket can become loose, corroded, or even damaged. When this disrupts the flow of electricity, your trailer lights may not work.

Fix: Inspect the connector for any damage, dirt, or debris. Clean the contacts with a wire brush and apply a dielectric grease to prevent future corrosion. Ensure the plug is securely fastened into the socket. If the connector is damaged beyond repair, replace it with a new one.

Trailer Safety Tips

While working lights are a top priority, here are some additional safety tips for hauling:

• Double-check your hitch. Ensure a secure connection between your tow vehicle and trailer.
• Inspect tires for proper inflation and wear. Underinflated or damaged tires can lead to blowouts and accidents.
• Distribute loads evenly. An unbalanced trailer can sway or tilt, affecting steering and control of your tow vehicle.
• Adjust your mirrors. Blind spots are magnified when towing a trailer. Consider installing wide-angle towing mirrors for better visibility.
• Practice safe driving habits. Maintain safe following distances, avoid sudden stops or abrupt lane changes, and be prepared for increased braking distances.

By following these tips and addressing common electrical problems, you can help ensure your trailer lights continue working, making your journey safe and productive.
