6. Maintenance
To ensure the longevity and optimal performance of your Auxbeam LED Light Bar, regular maintenance is recommended:
- Cleaning: Periodically clean the lens with a soft cloth and mild soap to remove dirt, mud, or debris that may obstruct light output. Avoid abrasive cleaners.
- Inspection: Regularly check all mounting hardware and electrical connections for tightness and corrosion. Ensure the wiring harness is free from damage.
- Waterproofing: The light bar features an IP68 waterproof rating and a breathable valve to prevent moisture buildup. Avoid submerging the light bar for extended periods or using high-pressure washers directly on the seals.
- Heat Dissipation: The aluminum alloy housing with heat sinks is designed for efficient heat dissipation. Ensure that the heat sink fins are not obstructed by debris or mud to maintain proper cooling.

7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Light bar does not turn on. | No power, loose connection, blown fuse, faulty switch. | Check power source, tighten connections, replace fuse, test switch. |
| Light output is dim or flickering. | Insufficient voltage, poor ground connection, damaged wiring. | Verify voltage (9-30V DC), ensure secure ground, inspect wiring for damage. |
| Moisture inside the lens. | Damaged seal, obstructed breathable valve. | Inspect seals for damage, clear any obstructions from the breathable valve. Allow to air dry. |
| Excessive heat from the light bar. | Obstructed heat sink fins, prolonged use in extreme temperatures. | Clean heat sink fins, ensure proper airflow. Reduce continuous operating time if necessary. |
