5. Operation
5.1. CL01 Rear Light Modes
The CL01 taillight features 5 distinct light modes for various riding conditions:
- High: 5 lumens, approximately 5 hours runtime.
- Low: 2 lumens, approximately 10 hours runtime.
- Warning Flashing: 30 lumens, approximately 9.5 hours runtime.
- Rapid Flashing: 5 lumens, approximately 11 hours runtime.
- Slow Flashing: 0.5 lumens, approximately 45 hours runtime.
Press the power button to cycle through the modes. Press and hold to turn off.

5.2. CL01 Brake Detection
The CL01 incorporates an intelligent brake sensing system. When you decelerate, the light automatically increases its brightness for 2 seconds to alert other road users behind you, enhancing safety. This feature does not function in slow flashing mode.

5.3. CL01 Smart Auto On/Off
This mode helps conserve battery power. If the light detects no movement for two minutes, it will automatically enter a sleep state. It will reactivate automatically when movement (vibration) is detected again, making it convenient for stop-and-go city traffic.

5.4. CL01 Wide Angle Visibility
The CL01 features a horizontal long light strip design, emitting 30 lumens with a 300-degree wide-angle beam. This design ensures you remain visible from multiple directions, not just directly from behind, enhancing safety in various riding environments.

5.5. Power Level Check (CL01)
When the CL01 light is off, a single click of the power button will display the current power level:
- Green light: Battery level > 40%
- Red light: Battery level 5% - 40% (Charge soon)
- Flashing Red light: Battery level < 5% (Charge immediately)

5.6. Charging
Both the FR500 and CL01 lights are rechargeable via USB. Connect the provided USB cable to the charging port on each light and plug the other end into a standard USB power source (e.g., computer, wall adapter). An indicator light will show charging status (typically red for charging, green for fully charged).
6. Maintenance
- Cleaning: Wipe the lights with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the lights in a cool, dry place when not in use. For long-term storage, charge the battery to approximately 50% every 3-6 months to prolong battery life.
- Water Resistance: The lights are designed to be water-resistant for typical cycling conditions. Avoid submerging them in water.
7. Troubleshooting
- Light not turning on: Ensure the battery is charged. If fully charged, try resetting by holding the power button for an extended period (e.g., 10 seconds).
- Light not charging: Check the USB cable and power source. Ensure the charging port is clean and free of debris.
- CL01 Auto On/Off not working: Ensure the light is in a mode that supports auto on/off. The sensor requires sufficient vibration to activate.
- CL01 Brake Detection not working: This feature does not operate in slow flashing mode. Ensure the light is in a compatible mode.
- Light flickering or dim: Charge the battery. If the issue persists, contact customer support.
