Restore Full Function to Trailer Lights

Wiring repairs and replacements for automobile trailers in Petrolia, Texas.

Your trailer's wiring controls the lights, brake signals, and turn indicators that keep you legal and visible on the road. In Petrolia, exposure to weather, road debris, and vibration can cause connections to corrode, wires to fray, and entire circuits to fail. When your lights stop working or your brakes don't signal properly, you risk citations and unsafe towing conditions.

How wiring repairs are handled

The trailer is connected to a test vehicle or diagnostic tool to identify which circuits are malfunctioning, and each wire is traced from the connector plug to the individual lights or brake assemblies. JB Manufacturing & Repair uses a multimeter to check continuity, voltage drops, and ground faults, then removes damaged sections and installs marine-grade wire rated for outdoor use.

After the repair, all lights will function as intended, brake signals will activate correctly, and the wiring will withstand moisture and vibration without failing. Properly sealed connections prevent water intrusion, which is the leading cause of recurring electrical problems in trailers.

If the entire harness is compromised, a full replacement is installed using factory-style routing and secure fastening to the trailer frame. This work applies only to automobile trailers and does not include RVs, campers, or heavy equipment. All wiring is tested under load before the trailer is returned to service.

Trailer owners in Petrolia often ask about the durability of wiring repairs, how long the work takes, and what causes electrical failures in the first place.

Common concerns about trailer wiring

What causes trailer wiring to fail?
Corrosion from moisture, abrasion from road debris, and stress from trailer flexing all contribute to wire failure. Poorly sealed connections and low-quality wire also accelerate breakdown.
How long do wiring repairs last?
Repairs using marine-grade wire and properly sealed connections can last several years, depending on trailer use and exposure. Regular inspections help catch issues before they lead to total failure.
Can you repair just one circuit or do you replace everything?
JB Manufacturing & Repair repairs individual circuits whenever possible to keep costs down. If the harness is extensively damaged, a full replacement may be more reliable.
Will the repair meet DOT requirements?
Yes, all wiring repairs are completed to meet federal and state safety standards for trailer lighting and brake signals. Your trailer will pass roadside inspections once the work is done.
How long does a wiring repair take?
Most repairs are completed in a few hours, but extensive damage or full harness replacements may require additional time. The timeline depends on the scope of the electrical fault.
