Can you wire an LED light bar without a relay?

This is a guide on how to wire an LED light bar without a relay. If you are wiring an LED light bar/off-road light from scratch you may want to avoid the hassle of connecting a relay as well when you install it.

How to connect LED light bar to power supply?

Tip: Never connect your LED light bar to AC current as it will damage it. Connect the light bar’s red wire to the positive side of the battery or power supply and the black wire to the negative terminal. If the light does not work, you need to take care of this problem before continuing with the installation.

How do you wire a rooftop LED light bar?

If you have a rooftop LED light bar, run the power wires through a windshield frame channel. Tip #7: Add a dual waterproof connector near the light bar for easy disconnection when the light needs to be removed. Tip #8: Use separate wire colors for different circuits so they are easily identifiable.

What are the two wires on an LED light bar?

Within each LED light there’s going to be two wires; a positive and a negative. These are what we call electrodes. In most LED light bars, the longer wire is going to be positive. Note: this is not always the case and you must first, before any other step, identify the two.

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.

Do you need a relay for LED spotlights?

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. Additionally, do you need a relay for spotlights? If your spotlight did not come with an electrical relay, you will need to install one.

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.

What is a relay switch 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.

What do you need to wire an LED light bar?

Despite, no matter what sort of LED light bar you’re looking to wire—or the power you want to connect to it—you’re going to need the above materials. Within each LED light there’s going to be two wires; a positive and a negative. These are what we call electrodes. In most LED light bars, the longer wire is going to be positive.

How to connect a light bar to a battery?

Connect the light bar’s red wire to the positive side of the battery or power supply and the black wire to the negative terminal. If the light does not work, you need to take care of this problem before continuing with the installation.

Which wire is positive on an LED light bar?

In most LED light bars, the longer wire is going to be positive. Note: this is not always the case and you must first, before any other step, identify the two.

How to wire LED light bar relays and switches?

This provides a greater margin of safety. Tip #4: When wiring LED light bar relays or switches, fuse all positive side wires such as from the positive battery terminal to the light bar switch. The fuse rating should not correspond to the wire size but instead to the maximum current expected on that wire.
