Mostly, people install these lights on the roof to get a clear view of the road in front of them. The manufacturer supplies the light bars with the complete installation kit. You will get the mounting brackets, mounting bars, screws, and other hardware products you are going to need for the installation. Make sure you check the quality of the mounting brackets. They must be capable of withstanding the damages from natural wear and tear, corrosion, and weather. The installation process could vary depending on the type of LED light bar you purchase. You must read the manufacturer’s manual and follow the instructions for proper installation. The light bar can come loose if you drive on bumpy and rough terrain. So, make sure they are fastened to the roof or above the bumpers tightly.
