5. Setup
5.1 Mounting the Headlight
The WEST BIKING headlight offers quick, tool-free installation with dual mounting options:
- Handlebar Mount: Attach the quick-release mount to your bicycle's handlebar. Ensure the rubber anti-slip patch is correctly positioned for a secure grip. The adjustable hole position allows for optimal alignment.
- Under Computer Mount: Utilize the dedicated bracket to mount the headlight beneath your bicycle computer, providing a streamlined setup.


5.2 Initial Charge
Before first use, fully charge the headlight using the provided Type-C data cable. Connect the cable to the headlight's Type-C port and a suitable USB power source (e.g., computer, power bank, wall adapter).

6. Operating Instructions
6.1 Power On/Off and Mode Switching
The headlight features a single button for control:
- Power On: Press and hold the power button for a few seconds until the light turns on.
- Switch Modes: Short press the power button to cycle through the available lighting modes: Strong Light, Medium Light, Low Light, and Flashing.
- Power Off: Press and hold the power button again for a few seconds until the light turns off.

6.2 Intelligent Light Sensing Mode
The headlight is equipped with an intelligent light sensor that automatically adjusts brightness based on ambient light conditions:
- When ambient light is strong, the brightness of the light decreases to conserve battery and prevent dazzling.
- When ambient light is dark, the brightness automatically increases to provide optimal visibility.

6.3 Charging the Headlight
To charge the headlight, connect the provided Type-C cable to the charging port on the device and to a USB power source. An indicator light will typically show charging status (e.g., red for charging, green for fully charged).
7. Maintenance
- Cleaning: Wipe the headlight body with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure the lens is clean for optimal light output.
- Storage: Store the headlight in a cool, dry place when not in use. If storing for an extended period, charge the battery every 3-6 months to maintain battery health.
- Battery Care: Avoid completely draining the battery frequently. Recharge promptly when the low battery indicator appears.
8. Troubleshooting
- Light not turning on: Ensure the battery is charged. Press and hold the power button for the required duration.
- Light not charging: Check the Type-C cable connection and the USB power source. Try a different cable or power source.
- Brightness issues in intelligent mode: Ensure the light sensor is clean and unobstructed.
- Headlight feels loose: Re-tighten the mounting bracket on the handlebar or check the speedometer bracket connection.
9. User Tips
- For optimal visibility and safety, especially during night cycling, consider using the highest lumen setting appropriate for your environment.
- Regularly check the battery level before long rides to avoid unexpected power loss.
- The IPX5 waterproof rating means it can withstand splashes and light rain, but it's best to avoid heavy downpours or submerging the light.
- Experiment with both mounting options (handlebar and under computer) to find the position that best suits your riding style and bike setup.
