5. Operating Instructions

The tail light features a single central button for control and intelligent automatic functions.

5.1 Power On/Off

• Power On: Short press the central button to turn the light on.
• Power Off: Short press the central button to turn the light off.

5.2 Light Mode Selection

With the light on, short press the central button to cycle through the 4 available light modes:

1. Flashing Mode
2. Breathing Flash Mode
3. Fast Flash Mode
4. Constant Light Mode

5.3 Brightness Adjustment

With the light on, long press the central button to adjust the brightness level. There are 3 levels:

• Low Brightness
• Mid Brightness
• High Brightness (Max 60lm)

5.4 Automatic On/Off Function

The tail light is equipped with an intelligent sensor that detects ambient light and vibration.

• Light Sensor (Daytime Mode): In bright conditions, the light will automatically turn off. In dark conditions, it will automatically turn on. This function is active only in Flashing and Breathing Flash modes during the day.
• Vibration Sensor (Nighttime Mode): If the light detects no vibration for 30 seconds, it will automatically turn off. When vibration is detected again (e.g., you start riding), it will automatically turn on. This function is active only in Flashing and Breathing Flash modes at night.

5.5 Brake Warning Function

The integrated high-sensitivity intelligent sensor chip detects braking. When braking is detected, the tail light will automatically illuminate at its maximum brightness (60lm) for approximately 3 seconds. This alerts vehicles and cyclists behind you to your deceleration, enhancing safety.

6. Charging

The tail light is equipped with a 400mAh rechargeable battery and uses a USB Type-C port for charging.

• Charging Process: Connect the provided USB Type-C cable to the light's charging port and to a USB power source (e.g., computer, wall adapter).
• Charging Indicator: During charging, the indicator light will flash. Once fully charged, the indicator light will remain constant.
• Battery Level Indicator: The light features a visual battery level indicator to show remaining charge (e.g., 75-100%, 50-75%, 25-50%, 0-25%). Recharge promptly when the battery level is low.

7. Maintenance

Proper maintenance ensures the longevity and optimal performance of your tail light.

• Cleaning: Wipe the light with a soft, damp cloth to remove dirt and dust. Do not use abrasive cleaners or solvents.
• Waterproof Care: The light is IP65 waterproof, meaning it is protected against dust and low-pressure water jets. While it can withstand rain, avoid submerging it in water. Ensure the USB port cover is securely closed when not charging to maintain waterproofing.
• Storage: Store the light in a cool, dry place when not in use. If storing for an extended period, charge the battery periodically to maintain its health.
• Material Durability: The aluminum alloy body is lightweight and robust, designed to withstand regular use.

8. Troubleshooting

If you encounter issues with your tail light, refer to the following common solutions:

• Light does not turn on:
  • Ensure the battery is charged. Connect to a USB power source and check the charging indicator.
  • Press the central button firmly.
• Automatic On/Off function not working:
  • Verify that the light is in Flashing or Breathing Flash mode, as these are the modes where the automatic functions are active.
  • Ensure the light sensor is not obstructed.
  • For vibration detection, ensure the bicycle is in motion.
• Light does not charge:
  • Check the USB cable and power source for proper connection.
  • Try a different USB cable or power adapter.
  • Ensure the charging port is clean and free of debris.
• Brake warning not activating:
  • Ensure the light is securely mounted and not loose, as this can affect sensor accuracy.
  • Test the braking action to ensure a clear deceleration is detected by the sensor.

9. Safety Precautions

Observe the following safety precautions for safe operation:

• Always comply with local road traffic laws and regulations regarding bicycle lighting.
• If your bicycle does not have a red reflector on the rear, use the constant light mode during nighttime riding. Flashing modes or colors other than red are considered auxiliary lights and should be used in conjunction with a red reflector.
• Do not look directly into the light when it is on, as it can cause temporary vision impairment.
• Keep out of reach of children.
• Do not disassemble or modify the product, as this may void the warranty and cause malfunction.
• Ensure the light is securely mounted before each ride to prevent it from falling off.
