Light Wiring & Harnesses
Wiring Harnesses and Switches
LED lights are the new standard: they give drivers brighter, more powerful, and safer lighting. Truck lighting accessories let you harness even more LED power. With a lighting harness and the right auto light switches, you can easily install light bars, work lights, or any other lighting accessory on your truck.

Measuring your bed
Put a tape measure inside the bed, from the inside of the bulkhead (front wall) to the inside of the closed tailgate. Round to the nearest inch — a 69" measurement is a 5'8" bed.
Bed length is measured inside the box, not along the outside of the truck.
Still unsure? Leave it blank to see every length that fits your truck, or call 888-865-4024.
If you want to install a light bar, or anything else, look for a lighting harness. A lighting harness lets you direct power to auxiliary lighting. Make sure you are using truck light wiring compatible with your vehicle.
Additional lights require new controls, and that is where light switches come in. Auto light switches let you make the most out of your new lighting accessories: you may be able to activate, dim, or redirect light. Look at our automotive electrical switches for ways to customize your LEDs.
