5. Setup and Installation
Follow these steps for proper installation of your LED light bar. Professional installation is recommended if you are unfamiliar with automotive electrical systems.
- Choose Mounting Location: Select a suitable location on your vehicle (e.g., roof, bumper) that provides clear light projection and secure attachment points.
- Attach Mounting Brackets: Secure the side mounting brackets to the light bar using the provided hardware. Ensure the brackets are oriented correctly for your desired mounting angle.
- Mount Light Bar to Vehicle: Fasten the light bar, with brackets attached, to your vehicle. The adjustable mounting brackets allow for 360-degree rotation to direct the light beam. Ensure all bolts are tightened securely to prevent vibration and movement.
- Wiring (Sold Separately):
- Connect the light bar to a compatible wiring harness (not included).
- Ensure the wiring harness includes a relay, fuse, and switch for safe operation.
- Connect the positive wire to the vehicle's power source (e.g., battery) via the fuse and relay.
- Connect the negative wire to a suitable ground point on the vehicle chassis.
- Route all wiring safely, away from moving parts and heat sources, and secure with cable ties.
- Test Functionality: Once installed and wired, turn on the light bar to verify proper operation. Adjust the angle as needed.

- Mounting Security: Verify that the mounting brackets and hardware remain securely fastened to the vehicle. Tighten if necessary.
- Water Resistance: The light bar has an IP67 waterproof rating, designed to resist dust and water ingress. However, avoid high-pressure washing directly at the seals.
- Heat Dissipation: The aluminum housing and cooling fins are designed for efficient heat dissipation. Keep the fins clear of debris to maintain cooling performance.
