Maintenance
Regular maintenance ensures optimal performance and longevity of your light bar:
- Cleaning: Clean the lens and housing regularly with a soft cloth and mild soap solution. Avoid abrasive cleaners that could scratch the lens.
- Inspection: Periodically check all mounting hardware for tightness. Inspect wiring for any signs of wear, fraying, or damage. Ensure all electrical connections remain secure and free from corrosion.
