5. Operating Instructions
Power On/Off and Mode Selection:
Press the power button located on the top of the light unit to turn it on. Subsequent presses will cycle through the available lighting modes. Press and hold the power button to turn the light off.
Lighting Modes:
The light features 4 distinct modes to suit various riding conditions:
- Floodlight: Provides a wide, even spread of light.
- Spotlight: Focuses light into a narrower, more intense beam.
- High Light: Combines floodlight and spotlight for maximum illumination.
- Flash: A flashing mode for increased visibility.

Digital Display Function:
The integrated digital display provides real-time information:
- Display 1: Use Time - Shows the remaining estimated operating time in the current mode.
- Display 2: Power% - Indicates the current battery charge level (0-100%).

Charging the Device:
The bicycle light is USB-C rechargeable. Connect the provided USB-C cable to the light's charging port and to a suitable USB power source (e.g., wall adapter, computer USB port). The digital display will show the charging progress.
Power Bank Function (LIG015 & LIG010 models only):
Certain models (LIG015, LIG010) can function as a power bank to charge other USB devices. Use the provided USB-A to USB-C adapter to connect your device to the light's USB-C port. The light's battery will then be used to charge your external device.

6. Maintenance
- Cleaning: Wipe the light unit with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the light in a cool, dry place when not in use. Avoid extreme temperatures.
- Battery Care: To prolong battery life, charge the device regularly, even if not used frequently. Avoid completely draining the battery before recharging.
- Water Resistance: The light is IPX5 waterproof, meaning it is resistant to water splashes and light rain. It is NOT designed for prolonged immersion in water or heavy downpours. Ensure the USB port cover is securely closed to maintain water resistance.
7. Troubleshooting
- Light not turning on: Check the battery level on the digital display. If low, recharge the device. Ensure the power button is pressed firmly.
- Light flickering or dim: This usually indicates a low battery. Recharge the device.
- Power bank function not working: Ensure the light itself has sufficient battery charge. Verify that the USB-A to USB-C adapter and charging cable are correctly connected.
- Water ingress: While IPX5 rated, avoid prolonged exposure to heavy rain or submerging the light. If water enters, turn off the device immediately and allow it to dry completely before attempting to use it again.
8. User Tips
- Handlebar Fit: Use the provided rubber spacers to ensure a tight and stable fit of the clamps on your handlebar. This prevents the light from shifting during rides.
- Battery Life: For longer rides, especially when using high lumen modes, consider carrying a portable power bank to extend the light's operating time, or choose a model with higher battery capacity like the LIG015 or LIG010.
- LIG013 Bracket: If you have the LIG013 model, the single included bracket is sufficient for stable installation. If you purchased an optional extension bracket, you can use it to adjust the mounting position further.
- Power Bank Use: When using the light as a power bank, monitor the light's battery level to ensure you have enough charge remaining for your ride.
