If your lightbar isn't lighting up, start by checking the red power line (+BAT) and the black ground-power line (–GND) to ensure they're properly connected to a fully charged 12-volt battery. Also, check the 40A fuse. Make sure the ground connection from the lightbar controller to the aluminum extrusion is secure. Finally, inspect the fuses on the lightbar controller.
