Operating Instructions


Press and hold the switch for 0.5s to turn the light on/off.

Output Selection

With the light switched on, single click the switch to cycle through Low, Med, High, Turbo

With the light switched on, double-click the switch to enter flash, single click to turn back to general mode

Battery level Indication

With the light switched off, single click the switch to check the battery status. The battery level indicators will display the battery status for 3 seconds.

One light on: critical, 0% - 25%

Two lights on: poor, 26% - 50%

Three lights on: sufficient, 51% - 85%

Four lights on: saturated, 86% - 100%


One standard Micro USB charging cable, which can be used for charging other digital devices, is included.

Charging operation: With the light switched off, remove the dust cover of the bicycle light to reveal the charging port, and plug the Micro USB end of the USB cable into the light's charging port, then connect the other end of the USB cable to a USB power adaptor

Charging Indicator: The indicators near the switch will display charging status. Four indicators will remain constant on when the battery is fully charged.

Please note:

Once charging is completed, be sure to remove the charging cable and replace the dust cover.

The normal charging time of the built-in battery is 2.5 hours from fully depleted to fully charged with the light off.

Recharge the light timely when the battery level is critical, for future use.

Recharge a stored light every three months to maintain optimal battery performance.

Only Low output can be used while the light is being charged, but charging time will be prolonged.

Intelligent Memory Circuit

The light memorizes the last selected brightness level on General mode. When turned on again the previously used brightness level will be recalled.

Overheat Protection

The light will accumulate a lot of heat when working on Turbo mode. The light will automatically step down a few lumens to reduce the temperature, but turbo mode can be selected.

Low-voltage Warning

One of the indicators flashes when the battery level is critical. When the voltage level drops below a preset level, the bicycle light is programmed to step down to a lower brightness level until Low output is reached. To ensure normal use, the bicycle light will work until the battery runs out.

Mounting Instruction

Unscrew the screw of the bike mount. Fix the bike mount in the desired position on the bike handlebar and fasten the screw.
