- Saddle Mount: Attach the rail adapter to the saddle rails, then clip the TR250 onto the adapter.
- Clip-on Mount: Use the clip-on adapter to attach the light to a backpack or other compatible gear.
4. Operating Instructions
4.1 Power On/Off and Mode Selection
The TR250 features a single button for control. Press the button to cycle through the lighting modes. A long press typically turns the light off or on, depending on the current state.
4.2 Lighting Modes and Runtimes
The TR250 offers 6 different lighting modes to suit various riding conditions and preferences:
| Mode | Brightness | Approximate Runtime |
|---|---|---|
| High Brightness | 40 Lumens | 3.5 hours |
| Mid Brightness | 20 Lumens | 8 hours |
| Low Brightness | 5 Lumens | 18.5 hours |
| Warning Flash | 250 Lumens | 4.5 hours |
| Rapid Flash | 100 Lumens | 9 hours |
| Slow Flash | 100 Lumens | 8.5 hours |
4.3 Intelligent Sensing (Auto On/Off)
The TR250 is equipped with a motion sensor for intelligent operation:
- Auto Off: If the light remains stationary for 2 minutes, it will automatically turn off to conserve battery.
- Auto On: Upon detecting vibration or movement from cycling, the light will automatically turn back on.
4.4 Brake Detection
When the light senses a reduction in speed (braking), it automatically increases its brightness to 100 lumens for 3 seconds. This serves as a clear warning to drivers and other cyclists behind you, significantly enhancing safety.
4.5 Power Indicator
The power indicator light provides information about the battery status:
- Blinking Blue: The light is currently charging.
- Constant Blue: The battery is fully charged.
- Blinking Blue (during use): Indicates that the battery power is less than 10%.
5. Maintenance
5.1 Charging
Regularly charge the TR250 to maintain optimal battery performance. Use the provided USB-C cable. Avoid over-discharging the battery for extended periods.
5.2 Water Resistance
The TR250 has an IPX6 water-resistance rating, meaning it is protected against powerful water jets. It is suitable for riding in heavy rain. Always ensure the USB-C charging port cover is securely tightened before riding to maintain its water resistance.
5.3 Cleaning
Clean the light unit with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these may damage the casing or lens.
6. Troubleshooting
- Light does not turn on:
- Ensure the battery is charged. Connect to a USB-C power source and check the charging indicator.
- Press and hold the power button for a few seconds to ensure it's not just in standby.
- Light turns off unexpectedly:
- Check battery level. Recharge if low.
- If the auto on-off function is active, ensure the light is detecting movement. If stationary for 2 minutes, it will turn off.
- Brake detection not working:
- Ensure the light is securely mounted and not loose, which could affect sensor accuracy.
- Test in a controlled environment with clear braking actions.
- Water ingress:
- Immediately turn off the light and allow it to dry completely.
- Ensure the USB-C charging port cover is always securely closed before exposure to water.
