How To Change A Off-Road Light Bar Fuse For Your Car

The process of changing a light bar fuse may seem complicated, but once you understand it, it won’t be too hard. Here’s a comprehensive fuse tutorial that will explain every aspect of fuses.

This guide explains everything in detail, so you’ll go from novice to pro in a snap.

We provide a free wiring harness with each product. We ensure the protection of their customers’ investments in our LED light bars and LED light pods.

An inline fuse in a waterproof case is integrated into the light bar wiring harness. It is possible to have the light bar fuse go bad due to its overwhelming power.

We will talk you through the testing and replacement process of replacing the LED light bar fuse, as our LED light bars have a lot of power.

What Is A Fuse?

A fuse protects an electrical connection from an abnormal current flow in electronic devices. As opposed to LED light bars, auxiliary fuses boxes or switch panels can connect them to LED light bars.

Is There A Reason For Fuse Ratings?

It would be best never to ignore the fuse rating since you need to protect your electrical circuit. Different circuits need different electrical currents.

One circuit’s amount of current may be too much for another. Ensure your circuit is protected.

What Is The Purpose of A Light Bar Fuse?

If an over-current event occurs, the fuse will melt the conductive metal strip enclosed inside it. It will drop the electrical connection.

Once the conductive strip is severed, no electricity will flow through it, which will prevent the light bar from getting damaged.

What Causes A Light Bar Fuse To Blow?

Checking For Blown Fuses

Lightbars can stop functioning due to a blown fuse, so it makes sense to examine that component first.

To understand why the light bar fuse blew, you will need to follow these three steps first:

  • Make sure the light bars are connected to the ground and power at the battery.
  • Make sure the light bars are connected to the DT connectors.
  • Upon finding no problems, check the entire harness on your truck to ensure no wires have been damaged.

  2. To get to the fuse, you need to open the light bar waterproof housing.
  3. make sure the metal strip on the fuse connects to the metal holder by pulling it out.
  4. The fuse should be replaced with one with the same rating.
  5. Close the fuse holder
  6.  Check to see if the light bar works now
