Can I wire my LED light bar?

You’ll most likely be wiring your LED light bar relay’s power lead directly to the battery, but you won’t necessarily use the same battery’s negative terminal as your ground.

Do I need a relay to wire a LED light bar?

A relay is an electrical switch that lets a low current circuit control a high current circuit such as a large LED light bar. If you are using a light pod that does not have a very large amp draw, you may not need a relay switch, but if you are using a larger LED light bar, they are a must have.

Why do LED light bars have a relay?

Relays can be used to switch a low-current trigger to high current, switch a circuit on or off, reverse polarity, and much more. When adding LED lights, such as off-road light bars, driving/work lights, or other auxiliary lights to a vehicle, you must add a circuit to power the light adequately.

What is a LED light bar?

An LED light bar is a particular type of electrical light fixture. It is characterized as being elongated and having several “bulbs” on it. Using an LED light bar can be a cost-effective light source for home owners, because LED light bars can be attached to each other and have a tendency to function many years after their purchase.

What is a switch harness?

Electronic Switch Harnesses are used to energize the electronic spark module at the proper knob rotation. The switch harness offers a reliable and feasible option when it comes to ignition switches.
