Setup and Installation
The XRIDONSEN emergency light bar is designed for easy installation on metallic vehicle roofs. Follow these steps for proper setup:
- Unpack Components: Carefully remove the light bar and all accessories from the packaging. Verify that all components, including the 16.4-foot power cable and controller cable, are present.
- Choose Mounting Location: Select a flat, metallic surface on your vehicle's roof for optimal magnetic adhesion. Ensure the area is clean and free of debris.
- Attach Light Bar: Position the light bar on the chosen roof area. The unit features 4 strong magnets with rubber suction cups to secure it firmly. Ensure all magnets make full contact with the roof surface.
- Route Cables: Connect the power cable and controller cable to the light bar. Route the cables safely into the vehicle's cabin, avoiding areas where they could be pinched, cut, or interfere with vehicle operation.
- Connect Power: Connect the power cable to a 12V power source in your vehicle. Ensure proper polarity.
