6. Setup and Installation
Note: Installation must be performed by a qualified mechanic or electrician to prevent electrical issues or fire hazards.
6.1. Preparation Work
- Turn off the vehicle ignition completely.
- Unpack the lamps and inspect all accessories to ensure they are present and undamaged.
6.2. Physical Installation
- Use the provided mounting hardware and appropriate tools to secure the lights to your vehicle's bumper, roof rack, or grille.
- Ensure the lens of each light is facing forward and is unobstructed for optimal light output.
6.3. Wiring Connection
Refer to the wiring diagram below for correct connections. The wire harness includes a relay and switch for safe operation.
- Connect the red wire (positive) and the black wire (negative) of the lamp to the corresponding wires on the vehicle's electrical system.
- DO NOT connect the lamps directly to the vehicle battery without a fuse.
- Connect the auxiliary switch to a suitable power source, typically an accessory wire located behind the dashboard, which is only active when the vehicle ignition is on.
- Connect the light and control cable assembly securely.
- For horn/overtake functionality, connect the positive terminal of the power supply to the speaker wire (for horn) or the overtaking lane wire (for overtake).

7. Operating Instructions
- Turn on the vehicle ignition.
- Turn the auxiliary switch (connected to the lights) to the "ON" position. The LED strip (DRL) should illuminate instantly.
- To change between different lighting modes (e.g., High Beam, Low Beam, Strobe, DRL), press the auxiliary switch repeatedly. The sequence of modes will cycle with each press.
- If connected, the horn function will activate the High Beam for 3 seconds when you honk your horn. The overtake function will turn on the High Beam when pressed.
Refer to Video 1 (above) for a visual demonstration of light mode changes.
8. Maintenance
- Cleaning: Turn off the light and allow it to cool for at least 15 minutes. Clean the lens with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the lens or housing.
- Storage: If you remove the lamps from your vehicle, store them in a dry, cool place away from direct sunlight and out of reach of children.
- Inspection: Periodically check all wiring connections for tightness and signs of wear or corrosion. Ensure mounting hardware remains secure.
9. Troubleshooting
If you encounter issues with your LED Work Auxiliary Headlights, consider the following common troubleshooting steps:
- Lights Not Turning On:
- Check all wiring connections to ensure they are secure and correctly connected (positive to positive, negative to negative).
- Verify that the vehicle ignition is on and the auxiliary switch is in the "ON" position.
- Inspect the fuse in the wiring harness. Replace if blown.
- Ensure the power source (accessory wire) is active.
- Incorrect Mode Cycling:
- Ensure the auxiliary switch is functioning correctly. Repeated presses should cycle through modes.
- Check for any loose connections in the switch wiring.
- Dim or Flickering Lights:
- Check for proper voltage supply (9-32V DC). Low voltage can cause dimming or flickering.
- Inspect wiring for corrosion or damage that might impede current flow.
If problems persist after performing these checks, it is recommended to consult a qualified electrician or contact customer support.
10. User Tips
- Brightness: Users have noted the lights are very bright at night, significantly improving visibility.
- DRL Use: Consider using the Daytime Running Light (DRL) mode during the day for increased visibility to other road users, even if not using the main driving beams.
- Wiring Harness: The included wiring harness simplifies installation, but ensure all connections are robust and protected from the elements.
- Off-Road vs. On-Road: Remember these lights are primarily for off-road or auxiliary use. Always be aware of local regulations regarding auxiliary lighting on public roads.
