2018 Dodge Ram 2500 LED Light Bar Installation: Bumper and Roof Mounts graph.org

The wiring for a roof-mounted light bar also requires additional attention. The cable should be properly protected where it passes through or along the vehicle body, and all connections should be sealed against moisture. Using an appropriate relay, fuse, and switch can help create a reliable electrical installation. Depending on the intended application, an LED light bar can be installed on the front bumper or mounted higher on the roof. Each mounting position offers different advantages, so choosing the right location depends on how and where the truck is used.
