4. Verification: Once installed, gently tug on the lens to ensure it is securely seated and does not wobble.

4. Operation

Once correctly installed, the replacement lens functions passively by covering the light source and providing a reflective surface. Its primary role is to protect the internal components of the light from environmental elements and to enhance visibility through its reflective properties, especially when the light is off.

5. Care and Maintenance

To ensure the longevity and effectiveness of your replacement lenses, follow these simple maintenance guidelines:

• Cleaning: Periodically clean the lens surface with a soft cloth and mild soap and water. Avoid abrasive cleaners or harsh chemicals that could scratch or damage the plastic.
• Inspection: Regularly inspect the lenses for any signs of cracks, chips, or discoloration. Replace any damaged lenses promptly to maintain optimal visibility and protection.
• Secure Fit: Occasionally check that the lens remains securely snapped into its housing, especially after long trips or exposure to vibrations.

6. Troubleshooting

If you encounter any issues with your replacement lens, consider the following common problems and solutions:

• Lens Does Not Fit:
  Possible Cause: Incorrect lens size or model.
  Solution: Verify the dimensions of your light housing against the lens specifications (3.88" x 2" x 1.13"). Ensure you have the correct replacement for your specific light model.
• Lens Falls Out Easily:
  Possible Cause: Improper installation or damaged housing/lens protrusions.
  Solution: Re-install the lens, ensuring the side protrusions snap firmly into place. Inspect both the lens protrusions and the housing slots for any damage. If damaged, replacement may be necessary.
• Reduced Reflectivity:
  Possible Cause: Dirt, grime, or scratches on the lens surface.
  Solution: Clean the lens thoroughly as per the maintenance instructions. If the lens is heavily scratched or discolored, it may need to be replaced.
