4. Operating Instructions
4.1 Power On/Off and Mode Switching
The XH01 features multiple operating modes and brightness settings:

- Power On: The lights will automatically turn on when motion is detected in dim environments (Smart Mode).
- Mode Switching: After powering on, short press the button to cycle through the 5 available flash modes: Red strobe, Yellow hazard lights, Purple strobe, Colorful flashing, and Red always-on.
- Brightness Adjustment: In the 'Red always-on' mode, press and hold the button to adjust the brightness. There are three brightness levels: Low, Medium, and High. Release the button at your desired brightness to set it.
4.2 Smart Mode and Manual Mode
The XH01 can operate in two primary modes: Smart Mode and Manual Mode.

- Switching Modes: Double-click the button to toggle between Smart Mode and Manual Mode. When in Smart Mode, a blue indicator light will be visible.
- Smart Mode Features:
- Smart Light Detection, Auto On/Off: Integrating high-precision photosensors, vibration sensors, and acceleration sensors, the lights detect changes in the riding environment (light, bumps, acceleration). They will automatically turn off when the environment is bright and turn on when it's dim. In Smart Mode, the lights will also auto turn off after 30 seconds of motionlessness and turn on when vibration is detected.
- Smart Brake Detection: When braking is detected, both the left and right lights will highlight simultaneously for 3 seconds to provide a clear warning to others.
- Team Synchronized Flashing: In Smart Mode, clicking one of the lights will synchronize the flashing of the remaining lights within a limited range. The flashing frequency remains consistent across all synchronized lights in the same lighting mode.


5. Maintenance
5.1 Charging
The XH01 lights come with a dual-port Type-C charging cable for convenient charging. Observe the blue indicator light for battery status:

- Blue light blinks once every 2s: 85%-90% battery remaining (Smart Mode).
- Blue light remains off: 85%-90% battery remaining (Manual Mode).
- Blue light strobe: Low battery, charging required.

5.2 Cleaning and Storage
- Cleaning: Wipe the lights with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Waterproof: The XH01 is IPX6 waterproof, meaning it is protected against high-pressure water jets from any direction. However, it is not designed for submersion.

- Storage: Store the lights in a cool, dry place when not in use for extended periods. Ensure they are fully charged before long-term storage to preserve battery health.
6. Troubleshooting

- Lights not synchronizing: Ensure both lights are in Smart Mode and within close proximity for team synchronization.
