3.1 Mounting Location
Select a suitable mounting location on your vehicle. Common locations include the roof, bumper, grille, or A-pillar. Ensure the chosen spot provides a clear beam path and does not obstruct vehicle operation or other lights.
Figure 3.1: Example of optional installation locations on a vehicle.
3.2 Bracket Assembly
- Attach the adjustable mounting bracket to the light bar using the provided screws.
- Secure the light bar with the bracket to your chosen mounting surface using the appropriate bolts, nuts, and washers.
- Ensure all connections are tight and secure to prevent vibration and movement during operation.
3.3 Wiring Instructions
The light bar features a three-wire connection for different lighting modes:
- Red Wire: Positive (+) connection for standard illumination.
- Black Wire: Negative (-) / Ground connection.
- Yellow Wire: Positive (+) connection for Flash Mode.
Connect the red wire to a 12V DC positive power source (e.g., battery, auxiliary switch) and the black wire to a suitable ground point. For flash mode, connect the yellow wire to a separate 12V DC positive power source or switch.
Figure 3.2: Wiring diagram for standard and flash modes.
3.4 Beam Angle Adjustment
The mounting bracket allows for 180-degree vertical adjustment. Loosen the bracket bolts, adjust the light bar to the desired angle, and then securely tighten the bolts.
4. Operating Instructions
4.1 Powering On/Off
Once wired correctly, activate the light bar by turning on the connected switch for the red wire (standard illumination) or the yellow wire (flash mode).
4.2 Lighting Modes
- Standard Illumination: Provides a powerful white light with a combo beam pattern (30° spot and 60° flood) for broad and focused illumination.
- Flash Mode: Provides a strobing light effect, useful for warning or signaling purposes.
