Truck lighting and electrical repair, Colorado
Lamps, wiring, and trailer harnesses traced and repaired. Lighting violations are quick to fix and easy to prevent.
Truck lighting repair in Colorado is one of the most common fixes we do, because lighting and wiring problems are one of the most common DOT violations. A dead marker lamp or a corroded trailer plug is a small thing that puts a truck out of service. The frustrating part is how avoidable it is.
We trace the fault to the source, whether it is a bulb, a ground, a connector, or a chafed wire, and we fix it so it stays fixed.
What we work on
Lighting and 12-volt electrical for medium-duty trucks and trailers.
Lamps and markers
Headlights, tail and brake lamps, turn signals, and clearance and marker lights replaced and aimed.
Trailer harnesses and 7-way plugs
The top source of trailer light trouble. We rebuild corroded plugs and harnesses instead of taping over them.
Wiring, grounds, and connectors
We chase shorts, opens, and bad grounds with a meter, not a guess.
Charging system
Alternators, batteries, and starters tested and replaced when they are behind a no-start or a dim light.
Switches and controls
Dash switches, relays, and fuses that drop out at the wrong time.
Accessory wiring
Work lights, beacons, and back-up alarms wired in clean.
DOT pass or fail, and uptime
Lighting is checked on every DOT inspection, and violations add up fast across a trailer. It is also the cheapest category to stay ahead of.
We fix the lights now so a five dollar lamp does not turn into a roadside out-of-service later.
One stop, not two
We run the DOT inspection and fix what it flags in the same shop. A lighting & electrical problem we find does not send you to a second vendor. We handle it and you leave road-legal.

Lighting & Electrical FAQ
Why do my trailer lights keep failing?
Most repeat trailer light failures trace back to a corroded 7-way plug, a bad ground, or a chafed wire rubbing through. We fix the cause so you are not replacing bulbs every month.
Is a single burned-out lamp really an inspection problem?
It can be, depending on which lamp. Required lamps that are out are a violation, and they add up across a trailer. We make sure every required light works.
Can you handle electrical problems beyond lighting?
Yes. We work on the charging system, grounds, switches, relays, and wiring for medium-duty trucks and trailers.
