Semi truck trailers are exposed to a tremendous amount of heat and pressure and tons of mud, sand, and debris. All parts of a trailer, including the lighting wiring harness, must be able to withstand the stress they undergo. Failure or damage in any of the components can undermine the lights' performance. We understand the full range of abuse your semi truck trailer endures and offer a range of reliable wires and components to keep your lighting system running, whatever comes your way. Whether you want to replace the old wiring, slightly upgrade the wiring system or get a custom harness assembly, we have you covered.
The wiring harness itself is an organized set of wires, terminals, and connectors that run all the way around the trailer and serve the purpose to carry power and transfer signals to various components of the lighting system, thereby playing a critical role in the overall operation. To put the highest grade products in the hands of our customers, we cooperate with prominent manufacturers using cutting-edge technologies and up-to-date equipment. Apart from wires on our digital shelves, you can find superior lighting modules, adaptor plugs, fuses, and relays. We also provide a host of grommets, brackets, gaskets, snap rings, sleeves, clamps, seals, and many, many more.

To help you securely connect your wires or cables and provide the terminals with necessary insulation we offer a bunch of high-grade connectors. They are resistant to the harsh environment and water intrusion. On our website, you can also get top-grade grommets used to protect the wires when they are routed through the trailer as well as to waterproof the wires if the sealing agent is provided below it. The grommets are impervious to chemicals, salt sprays, and heat. To support and fix up wires firmly, choose from our first-rate clamps. And to keep cables manageable in the assembly, get superior wire harness clips.
Apart from high dependability, the wires ensure ease of use and maximum effectiveness. They offer effortless and worry-free installation that won't take much of your time.
