Is a relay required for LED lights?

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.

Can you wire LED light bar without relay?

Yes, one can wire an LED light bar without a relay. If you are not sure about the switch, fuses and wiring being of the right size for the amperage, then you should use a relay to avoid something bad happening.

What is a LED flasher relay?

The LED flasher unit is a solid state electronic device that is specifically designed for use on vehicles fitted with LED lights. Additionally, the flasher relay has the unique ability to control the flash rate of the vehicles LED directional indicators.

Can you wire LED light bar without Relay?

Why use a relay instead of a switch?

While a relay does add an extra step to the switching process, the main advantage is that you can leave the actual switching of high-power circuits for things like off-road lights or air compressors in the engine compartment, and control that switching with a much smaller amperage circuit that energizes the relay’s …

When would you use a relay?

One of the most common situations that require the use of a relay occurs when an application needs to switch from high to low current (or vice versa) within the same circuit. For example, the temperature sensors that power HVAC units require levels of amperage that vastly exceed the capacity of their wiring.

How do I wire a high beam light to a relay?

With our wiring harness, all you need to do is cut the wire coming from the switch to the 30 prong on the relay, and wire it to your high beam lead or your backup light wire.

Can I use a relay to turn on the lights?

Still fine for your lights. A relay is just an electrically operated switch. Basically what happens is that small wiring and a small switch in the dash or wherever are used to turn on/off a bigger switch (the relay) that can handle lots of amps and has big wires running to and from it.

What is a relay?

A relay is an electrical switch. It allows a low current “switch” circuit to control the electricity flow of a high-current circuit load, like your LED Light bar for example. Why Do I Need A Relay?

Where does the Red Wire go on an LED light bar?

For these reasons, the red wire is tapped into the headlight positive wire. Step 7: Test Your LED Light Bar to Make Sure Your Wiring Is Done Correctly.
