Maintenance and Troubleshooting

Regular maintenance ensures optimal performance of the hazard light switch. Follow these guidelines to keep your system in top shape.

• Visual Inspection: Periodically check for signs of wear, corrosion, or loose connections. Replace any damaged components immediately.
• Clean Contacts: Use a soft brush and isopropyl alcohol to remove dust from the switch contacts. Avoid abrasive materials that could scratch metal surfaces.
• Test Functionality: Once every six months, activate the hazard lights to confirm all lamps are functioning correctly. If any lamp fails, inspect wiring for continuity.
