Installation Guide

1. Mounting the Light Bar

1. Choose a Location: Select a suitable mounting location on your vehicle (e.g., bumper, bull bar, roof rack) that provides clear visibility and does not obstruct other vehicle functions.
2. Position Brackets: Place the mounting brackets in the desired position and mark the drilling points. Ensure the light bar will be level and securely supported.
3. Drill Holes: Using a 1/4-inch drill bit, carefully drill pilot holes at the marked locations. For switch installation, a 3/4-inch hole saw may be appropriate, with a small file or grinder to create a notch for the switch's locating rib.
4. Secure Brackets: Attach the mounting brackets to the vehicle using the provided bolts, washers, and nuts. Tighten securely.
5. Attach Light Bar: Mount the LED light bar to the secured brackets using the remaining hardware. Adjust the angle as needed for optimal light direction, then tighten all fasteners.

2. Wiring the Light Bar

The included DT wiring harness simplifies the electrical connection. If you are unfamiliar with automotive electrical systems, professional installation is recommended.

1. Disconnect Battery: Before starting any wiring, disconnect the negative terminal of your vehicle's battery to prevent electrical hazards.
2. Connect Light Bar to Harness: Connect the DT connector from the light bar to the corresponding DT connector on the wiring harness. Ensure a firm connection.
3. Connect Power and Ground:
   • Connect the red wire from the harness to a positive 12V power source (e.g., directly to the battery's positive terminal or an auxiliary power distribution block). The harness includes an inline fuse for protection.
   • Connect the black wire from the harness to a suitable ground point on the vehicle chassis or the battery's negative terminal.
4. Install Switch: Route the switch wire to your desired location within the vehicle's cabin. Install the switch in a convenient and accessible spot.
5. Connect Relay: The harness includes a relay. Ensure it is mounted in a dry, secure location away from excessive heat or moving parts.
6. Secure Wiring: Route all wiring safely, away from hot engine components, sharp edges, and moving parts. Use zip ties or cable clamps to secure the wires.
7. Reconnect Battery: Once all connections are secure and verified, reconnect the negative terminal of your vehicle's battery.

Operation

To operate the 4WDKING LED Light Bar, simply activate the installed switch. The light bar will illuminate, providing auxiliary lighting. Turn off the switch when auxiliary lighting is no longer required.

Note: Always be aware of local regulations regarding the use of auxiliary lights on public roads.

Maintenance

• Cleaning: Periodically clean the lens of the light bar with a soft cloth and mild soap and water to maintain optimal light output. Avoid abrasive cleaners or harsh chemicals.
• Inspect Connections: Regularly check all electrical connections for corrosion or looseness. Ensure the DT connector is clean and securely fastened.
• Check Mounting: Verify that the light bar and its mounting brackets remain securely attached to the vehicle. Tighten any loose bolts as needed.
• Breather Valve: The military-grade breather valve helps prevent moisture. Ensure it is not obstructed by dirt or debris.
