Trailer Wiring & Lighting Repair in Henderson & Las Vegas
We repair trailer wiring and lighting where the trailer is parked in Henderson, Las Vegas and Boulder City: tail lights, brake lights, turn signals, connectors, grounds and 7-pin plugs. Most lighting problems come down to a bad ground, a corroded connector or a damaged wire, and a technician can usually find it in one visit.
Symptom checklist
Trailer light and wiring trouble
If you recognize two or more, a technician can usually tell you the cause in one visit.
- Tail lights, brake lights or turn signals out
- Lights flicker or only work when you wiggle the plug
- Turn signals flash too fast or too slow
- Brake lights stay on, or the left and right sides are swapped
- Blown fuses on the tow vehicle every time you plug in
- Corroded or melted plug on the trailer or tow vehicle
- The trailer battery does not charge while you tow
- Frayed, cracked or dangling wires under the trailer
What we do
What does a mobile technician do for trailer repair?
Lighting diagnosis
- We test the circuit from the tow-vehicle connector back to each light, checking power, grounds and connections in order.
Connector and plug repair
- New 4-way flat and 7-way plugs, repaired sockets, and adapters that match your tow vehicle.
Wiring repair and harnesses
- Repair of damaged wire, new sections or full harness replacement, routed and secured so it stays clear of the road.
LED light upgrades
- Sealed LED tail, marker and clearance lights that hold up better to heat, vibration and water.
Ground and charge-line fixes
- Clean, solid grounds and the charge wire that keeps your trailer battery topped up on the road.
Desert-specific
Why do trailer lights fail in Las Vegas heat and dust?
Sun and heat dry out wire insulation until it cracks, and dust and moisture work into plugs and sockets. Add vibration on a long drive and a connector that looked fine in spring can fail in July. Sealed LED lights and protected wiring last much longer.

FAQ
Trailer Repair questions
Why are my trailer lights not working?
The most common causes are a bad ground, a corroded plug or socket, a blown fuse on the tow vehicle, or damaged wire. We test each to find the real cause instead of replacing parts at random.
Can you convert my trailer to LED lights?
Yes. We replace the lights and check the wiring they connect to, so the new lights work reliably on your tow vehicle.
Do you repair boat trailer lights?
Yes. Boat trailer lights and connectors suffer from water and corrosion, so sealed LED lights and protected connections are a good fix.
Do you repair trailer brakes, bearings or axles?
No. Our trailer service is wiring and lighting. For brakes, wheel bearings and axles, use a trailer shop.
Can you fix my trailer wiring at a storage lot or home?
Yes. We bring the tools and come to your lot or driveway. Tell us the trailer type and what the lights are doing when you book.
