The Process of Installation LED Light Bar on Roof

Now that you know which tools you need for the project let’s now head over to the simple guide for installing the light bar onto your truck’s roof.

Use a Marker to Identify the Mounting Location

To get the optimal mounting location, use the mounting brackets to preassemble the unit before laying it across your truck’s roof. There is always the risk of the mounting brackets ruining your car’s paint, and this is where a masking tape would come in handy.

Drilling the Holes

The next step involves drilling the holes, and you should follow the pattern laid out by the designated dots. Do not forget to remove the masking tape.

Securing the Brackets

With the holes in place, align them and the mounting brackets so that you can secure them to the car’s frame well. You can now mount the brackets, using the right tools, some of which are included in the package.

Mount the LED Bar

Now that the brackets are secured on the roof, it is now safe to mount your unit onto them.


This part may be complicated for some, especially if you lack wiring experience. However, you can count yourself lucky that most packages include a guide on installing a relay harness kit with an on/off switch and how you can connect wires to the kit.


The last step involves testing your product to be sure that it functions as it ought to. If everything clicks, you can now enjoy the benefits that the fixture brings.
