Light bar relay hook up

How to wire a relay for LED light bar?

In order to wire a relay for the LED light bar, you’ll need a battery, a switch, and of course a relay. After arranging all these components, follow the below mentioned step-by-step guide. First of all, connect the outlet or pin number 30 on your relay to the positive terminal of the battery.

How to connect a battery to a light bar?

In order to connect it with the light bar, follow and implement the below circuit diagram: Firstly, connect the positive terminal of the battery through the fuse to pin 30 of the relay. Take an ignition switch and connect it to pin 86 of the relay.

How to connect a battery relay to a switch?

After properly connecting the positive terminal, connect the pin number 85 on the relay to the negative terminal of the battery. Now, the relay is perfectly connected with the battery. The next step would be to connect pin number 86 of the relay to the switch controlling the whole circuit.

Why do I need a relay for a light switch?

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. Another reason you may want a relay is for the creative ways you can use electrical currents from things other than a physical switch.

How to connect a battery to a light bar?

Do I need a relay for my light bar?

Another reason you may want a relay is for the creative ways you can use electrical currents from things other than a physical switch. Lets say you want have your LED Light Bar come on with your high beams, or reverse lights, for example. Read more about that below.

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.

How to connect a battery relay to a switch?

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 relay used for?

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.

Why are relays better than switches?

Here are some reasons why relays are better than switches: A correctly wired relay will provide the shortest electrical path (i.e. shortest wire length) between the battery and the device(s) controlled by the relay.

What are switches and relays in Electrical Engineering?

In electrical engineering, both switch and relays are important electrical components. They are electromechanical devices designed to control and protect the system. They can be found in many home electrical applications, in industries such as automotive, telecommunication, power system and control system industries.
