6. Maintenance

• Cleaning: Wipe the headlight body with a soft, damp cloth. Do not use abrasive cleaners or solvents, as they may damage the finish or internal components.
• Waterproof Seal: Always ensure the USB port rubber cover is securely closed when not charging to maintain the IPX6 waterproof rating.
• Storage: Store the headlight in a cool, dry place when not in use. If storing for extended periods, charge the battery to about 50-70% every few months to prolong battery life.
• Battery Care: Avoid fully depleting the battery regularly. Recharge it when the charge is low to maintain optimal battery health.

7. Troubleshooting

• Light Does Not Turn On: Ensure the battery is charged. Connect to a power source and check if the charging indicator appears. If not, try a different USB cable or power source.
• Light Flickers or Is Dim: This usually indicates a low battery. Recharge the headlight fully.
• Mount Is Loose: Re-tighten all screws on the handlebar mounting bracket and ensure the headlight is securely clicked into place. If the mount continues to be unstable, inspect for damage.
• Charging Not Working: Check the USB cable for damage and ensure it's properly connected to both the light and the power source. Verify the power source is active.

8. User Tips

Based on user feedback, here are some tips for an optimal experience:

• Mount Stability: Some users find the stand sensitive. For extra stability, especially on rough terrain, consider reinforcing the mount or using a secondary mounting point if possible.
• Power Button Response: Be aware that the power button may require a sustained press (a few seconds) to turn the light on or off.
• Brightness for Conditions: Utilize the different modes (Floodlight for wide visibility, Spotlight for focused distance, High Light for maximum illumination, Flash for daytime visibility or emergencies) according to your riding conditions.
