Service Schedule
Unlike many vehicle components, headlamp dimmer switches don't have a specific maintenance schedule. They are generally considered "service when failed" components. However, we recommend:
- Annual Inspection: Have the switch checked during routine maintenance
- Cleaning: For automatic systems, clean the sensor every 6 months
- Testing: Check functionality every 3 months, especially before long trips
Note: If you experience any of these symptoms, it's important to have your vehicle inspected by a qualified technician to prevent potential safety issues while driving at night.
