Electrical accessories matter more than most enthusiasts realize.

Relay harnesses draw power directly from batteries using factory switches triggering relays-this protects electrical systems while ensuring lights receive full voltage without voltage drops reducing brightness. Wire gauge matters critically-undersized wiring heats excessively under load potentially causing fires, while proper sizing handles current safely. Fuses protect circuits-always include inline fuses preventing short circuits from causing catastrophic damage.

Take control of all your additional lights and devices using our light switches and wiring options at American Trucks. It's a lot of fun to add a bunch of accent lights and accessory lights throughout your truck's interior, but it can be a hassle trying to turn the lights on and off depending on how you have them set up. The best solution to this issue is to just utilize our wiring and Sierra light switches to efficiently control the various lights around your cabin. By installing switches you can remotely control the different lights all throughout the cabin, making them much easier to make use of. Add switches to comfortable locations for lights that are in awkward locations to make sure you can activate them when you need them. You can also add more than one light on a single switch if you want to turn on many accent lights at the same time or reduce the number of switches that you have inside your truck. We offer a bunch of Sierra gauges as well and other truck interior parts, and you can control all that stuff with the light switches that we make available to truck owners. Invest in these switches for yourself and you'll have the necessary control that you need to flip all your accessories on and off with ease. You can even get switches in different colors to make them easy to recognize so you know which one to turn on and off to run the different items in and out of your vehicle properly.
