- To use as a power bank, connect your device to the headlight via a Type-C cable.

5. Maintenance
5.1 Cleaning
- Wipe the headlight body with a soft, damp cloth.
- Avoid using abrasive cleaners or solvents that could damage the aluminum alloy shell or PC lens.
- Ensure the charging port cover is securely fastened before cleaning or exposing to water.
5.2 Waterproofing
The headlight has an IPX6 waterproof rating, meaning it is protected against high-pressure water jets from any direction. However, it is not designed for submersion.
- Always ensure the Type-C charging port cover is tightly closed, especially in rainy conditions or when washing the bike, to maintain its waterproof integrity.

5.3 Battery Care
- Charge the battery fully before first use.
- Avoid completely draining the battery frequently to prolong its lifespan.
- If storing the headlight for an extended period, charge it to approximately 50-70% and recharge every 3-6 months.
5.4 Temperature Control
The device features intelligent temperature control. It will automatically reduce output power if the internal temperature exceeds 65℃. If the temperature drops below 55℃, it will automatically return to the original gear. The device will automatically turn off if the temperature exceeds 85℃ to prevent damage.
6. Troubleshooting
6.1 Light Not Turning On
- Ensure the battery is charged. Check the power indicator light.
- Long press the power button for 0.5 seconds.
6.2 Light Output is Low or Flickering
- The battery might be low. Recharge the device.
- The device might be in temperature control downshift mode if it's overheating. Allow it to cool down.
6.3 Device Not Charging
- Ensure the Type-C cable is properly connected to both the headlight and the power source.
- Try a different Type-C cable or power adapter.
- Check if the charging port is clean and free of debris.
6.4 Handlebar Fit Issues
The headlight comes with two types of brackets (Handlebar Style and Integrated Style) to accommodate various handlebar designs. If you encounter difficulty mounting the headlight, ensure you are using the correct bracket for your handlebar type. The product specifications do not list specific handlebar diameter compatibility, but the Handlebar Style bracket is designed for standard round handlebars. If your handlebar is non-standard (e.g., 35mm diameter), you may need to verify compatibility or seek alternative mounting solutions.
