The CYCLAMI Bicycle Front Light offers versatile mounting options to suit your preference and bicycle setup. Both BR500 and BR500T models include strap-on brackets.
General Installation (BR500 - Positive Mounting)
- Secure the strap bracket to your bicycle's handlebars. Ensure it is tight and stable.
- Slide the bicycle light onto the bracket until it clicks securely into place.

Suspension Mounting (BR500T - Downward-facing)
The BR500T model supports suspension mounting, often used with extension brackets (sold separately) for a downward-facing orientation, which can be integrated with cycle computers.

Operating Instructions
The bicycle light features a single button for power and mode selection.

- Power On/Off: Press and hold the power button to activate or deactivate the light.
- Switching Modes: Once powered on, click the button to cycle through the standard lighting modes:
- High Light
- Medium Light
- Low Light
- Flashing
- Emergency Gear: Double-click the button to switch to the highlight mode. In this mode, the brightness will not change with the power level. Click the button once to exit the emergency gear.
- Alert/Warning Mode: Press the button three times in quick succession to switch to the blinking (alert) mode.

Battery and Charging
Battery Level Indicator
The power indicator light on the device provides a visual cue for the remaining battery level:
| Indicator Light Colour | Remaining Power |
|---|---|
| Green (solid) | 50% - 100% |
| Green (flashing) | 10% - 50% |
| Red (flashing) | 0% - 10% |
Charging Instructions
- Use the provided TYPE-C charging cable to charge the device.
- During charging, the indicator light will flash red.
- Once fully charged, the indicator light will turn solid green.
- Ensure the rubber plug at the charging port is fully embedded before use to maintain IPX6 waterproof rating.
- Approximate charging time is 2.5 hours.


Maintenance
- Keep the light clean from dirt and debris. Use a soft, damp cloth for cleaning.
- Ensure the Type-C charging port's rubber plug is always securely closed when not charging to maintain its IPX6 waterproof rating.
- Store the light in a cool, dry place when not in use for extended periods.
- Avoid exposing the light to extreme temperatures.

Troubleshooting
If you encounter any issues with your CYCLAMI Bicycle Front Light, please refer to the following common solutions:
- Light not turning on: Ensure the battery is charged. Connect the light to a power source using the Type-C cable and check if the charging indicator activates.
- Light modes not changing: Ensure you are clicking the button correctly. A single click cycles modes, a double-click activates emergency highlight, and three quick clicks activate alert mode.
- Reduced brightness or short endurance: The battery might be low. Recharge the light fully. Battery performance can also be affected by extreme cold.
- Light head getting hot: It is normal for the lamp head to dissipate heat during prolonged use, especially in high light mode. This is a normal phenomenon and not a defect.
If the problem persists, please contact customer support.
User Tips
- For optimal visibility and safety, use the High Light mode in dimly lit environments and the Flashing mode for daytime visibility or as a warning.
- Regularly check the mounting bracket to ensure the light is securely attached before each ride.
- Always fully charge the light before long rides to maximize endurance.
Safety Information
- Eye Safety: Do not shine the light directly into your eyes or the eyes of others. The high intensity of the light can cause temporary vision impairment or discomfort.
- Heat: The lamp head will dissipate heat and may become warm during prolonged use. This is normal. Avoid touching the lamp head directly when it is hot.
- First Use: For normal operation, please charge the bicycle light fully before its first use.
- Waterproof: The light has an IPX6 waterproof rating, meaning it is protected against powerful water jets. However, it is not designed for submersion. Ensure the charging port cover is sealed.
