Trailer Wiring & Light Repair Jerome, Idaho
Trailer wiring and light repair in Jerome, Idaho keeps our bays busy, because lights are the number one thing officers spot from the patrol car. One dead marker light is a DOT lighting violation. We fix 7-way cords, bad grounds, shorts, and flickering lights on dry vans, flatbeds, cattle pots, and tankers.
What does trailer wiring repair include?
We repair and replace 7-way cords and plugs, sockets, junction boxes, harnesses, and lights — marker, clearance, brake, turn, and license lamps. We chase shorts and dead circuits back to the real cause instead of just swapping the bulb that's out.
Nine times out of ten, the real problem is a bad ground. Corrosion builds up where the harness grounds to the frame, and lights start flickering or going dim. We clean and rebuild grounds so the fix lasts, not just until the next wet road.
Should I convert my trailer lights to LED?
If your trailer still runs incandescent bulbs, an LED conversion is worth a look. LEDs pull less power, run brighter, and shrug off the vibration that kills filament bulbs. Fewer burned-out lights means fewer violations and fewer roadside stops. We can convert the whole trailer or just the lamps that keep failing. Ask for a quote — the price we quote is the price you pay.
How long does light repair take?
Simple jobs — a lamp, a pigtail, a 7-way end — are usually done while you wait. Chasing a short through a harness takes longer, since the break can hide anywhere along the trailer. We'll tell you what we found and quote the fix before we start. Open 7 AM to 10 PM every day, so you can come in after you drop a load.
Winter is hard on trailer wiring
Magic Valley winters coat I-84 in salt, sand, and mag chloride, and all of it eats connectors and grounds. That's why light problems pile up from November to March. If your lights act up every time it snows, that's moisture in the wiring — bring it in before an inspector finds it first. We also run mobile calls from Bliss to Declo for trailers stuck at a dock with no lights.
Driver questions
My trailer lights work sometimes and not others. What is that?
Almost always a bad ground or a worn 7-way cord. Wiggle the cord at the plug — if the lights flicker, you found it. We repair the cord, the socket, or the ground so the lights work every time you plug in.
Can I get a ticket for one marker light being out?
Yes. Any required lamp that's out is a lighting violation, and it gives an officer a reason for a full inspection. Fixing a marker light is cheap. What the inspection finds after the stop might not be.
Do you do LED conversions?
Yes. We convert incandescent trailer lights to LED — the whole trailer or just the problem lamps. You get a quote first, and the price we quote is the price you pay.
