Having a relay switch is essential if you are wiring up a light bar that has a very large amp draw at all. 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 your light has a very large amp draw at all, you will want to install a relay switch to keep from overheating an ordinary switch, burning up the wires, and thus reducing the amount of electricity getting to your light. 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.

How to Wire a Relay for Off-Road LED Lights by Robert Reynolds
A common question we get is, "What is the relay for and how do I wire it up? A relay is an electrical switch. When you create a circuit a loop of electricity from the battery to your LED Light bar , if you just put a switch between the battery and the light, it will have to be rated for the full current amp draw of the light. Many switches would be able to handle that As a result, you could end up overheating the switch, melting the wires, and reducing the current that is getting to your lights, making them not as bright.

Once you have mechanically installed your new LED light bar, it is time to give it a steady supply of electrons so it has a steady supply of night vanquishing power. Learning how to wire and LED light bar correctly ensures reliability and avoids unsafe operating conditions or damage to your vehicle. Tip 1: Please do not skip over this section unless you have a great deal of experience with electrical wiring and components.
