10 Simple Step-by-step Guidelines on How to Wire a Led Light Bar

Step 1: Determine the Location of Your Led Light Bar

Before you start the wiring process, determine where you want to install your LED light bar. Choose a location that allows for easy access to the power source and switch. It is also crucial to ensure that the light bar does not obstruct your view while driving. It should be mounted securely and at a height that provides maximum illumination.

Step 2: Mount the Led Light Bar

Using the provided hardware, mount the LED light bar in place. Be sure to follow the manufacturer’s instructions for proper installation. But before you secure it in place, make sure to leave enough slack in the wiring so that it can reach the switch and power source comfortably. Therefore, it is essential to keep the mounting location in mind while determining the wire length.

Step 3: Prepare the Wiring

Using the wire strippers, strip off about half an inch of insulation from both ends of the wires (negative and positive) on your LED light bar. Ensure that there is no exposed wiring as it can cause a short circuit.

Otherwise, use electrical tape to insulate the exposed wires. But remember, using crimp connectors is a better option. You can also use a wiring harness for easier and more organized installation. But whichever method you choose, make sure to follow the manufacturer’s instructions.

Step 4: Locate and Prepare the Power Source

Locate the power source you will be using to connect your LED light bar. This could be from an existing wiring harness or directly from the battery. Whatever the case, make sure to use appropriate fuses to protect both your vehicle’s electrical system and the LED light bar.

It is best to consult a professional electrician if you are unsure. This step may also require you to drill a hole into your vehicle’s firewall, so make sure to do it correctly.

Step 5: Connect It from the Light Bar to the Relay

Using a suitable size wire, connect the positive wire from your LED light bar to one of the terminals on the relay. Most relays have four or five terminals, and it is essential to follow the manufacturer’s instructions for proper wiring.

But in most cases, the positive wire from the light bar will connect to the terminal labeled 87. You can then use zip ties or cable clamps to secure the wire in place. It is also a good idea to wrap the connection in electrical tape for added protection.

Step 6: Grounding

Proper grounding is vital for optimal functionality and safety. Locate a suitable grounding point on your vehicle’s chassis and connect the negative wire from the LED light bar.

 Connect the Negative Wire From the Led Light Bar

Although the chassis is an excellent choice for grounding, you can also use a dedicated grounding wire connected to the battery’s negative terminal. This will ensure a strong and reliable ground connection. it is essential to avoid grounding the light bar directly to the battery as it can cause damage.

Step 7: Connect the Power from the Relay to

Using another suitable size wire, connect the positive wire from the relay to a power source with an appropriate fuse. This will provide power to the relay and, in turn, the LED light bar. But remember to consult a professional electrician if you are unsure about the power source.

If using an existing wiring harness, follow the manufacturer’s instructions for proper connection. However, in most cases, the positive wire from the relay will connect to a power source with an appropriate fuse.

Step 8: Connecting the Switch

Using another suitable size wire, connect one end to the remaining terminal on the relay and the other to your desired location for the switch. This will allow you to control when your LED light bar is turned on or off.

It is best to choose a location that is easily accessible for you while driving. Whether you choose to mount the switch on your dashboard or console, make sure it is securely attached. You can also use an on/off switch with an LED light to indicate when the light bar is turned on.

Step 9: Test Your Wiring

Before finalizing everything, it is crucial to test your wiring. Connect the negative wire from the LED light bar to the battery’s negative terminal and then connect the positive wire from the switch to the positive terminal.

If everything is working correctly, you are good to go! It is also essential to check for any loose connections or exposed wiring and fix them before using your LED light bar. But if something is not working correctly, consult a professional electrician.

Step 10: Secure Your Wiring

Once you have confirmed that everything works as intended, use zip ties or cable clamps to secure the wiring in place. This step will ensure that your wiring stays neat and organized and does not get tangled or damaged while driving. Always make sure to double-check all connections and secure them properly.

Follow these simple steps on how to wire a led light bar, and you will have your LED light bar wired up in no time! Remember to always follow the manufacturer’s instructions for proper installation and safety precautions. Enjoy your new LED light bar and the extra illumination it provides on your adventures! Happy wiring!
