6. Maintenance

To ensure the longevity and clear visibility of your signal light assembly, follow these simple maintenance guidelines:

• Regular Cleaning: Periodically clean the outer lens with a soft cloth and mild automotive soap to remove dirt, dust, and road grime. Avoid abrasive cleaners or harsh chemicals that could damage the polycarbonate material.
• Inspect for Damage: Routinely check the assembly for any signs of cracks, chips, or moisture intrusion. Address any damage promptly to prevent further issues.
• Bulb Check: If the signal light stops functioning, first check the bulb. Bulbs have a finite lifespan and may need replacement. Ensure the correct bulb type is used as specified by your vehicle manufacturer.

7. Troubleshooting

If you encounter issues with your signal light assembly, consider the following common troubleshooting steps:

• Light Not Working:
  • Verify the bulb is correctly installed and not burnt out.
  • Check the electrical connection to ensure it is secure and free of corrosion.
  • Inspect the vehicle's fuse box for a blown fuse related to the turn signals.
• Poor Fitment:
  • Ensure all mounting tabs and clips are properly aligned and engaged.
  • Confirm that no debris or obstructions are preventing the assembly from seating correctly.
  • Double-check that you have the correct part for your specific vehicle year and model.
• Moisture Inside Lens:
  • While the product is designed to be waterproof, extreme conditions or improper installation can sometimes lead to condensation. Ensure the rubber seal around the assembly is properly seated and not damaged.
  • If condensation persists, remove the assembly, allow it to dry thoroughly, and re-install, paying close attention to the seal.

If these steps do not resolve the issue, please contact customer support.
