Low-voltage Warning
The functional switch will flash red to remind to replace the batteries when the voltage level
drops below a preset level. The bicycle light is programmed to step down a few lumens to
prolong the runtime and the light will not turn off automatically.
Note: This may not work if 4*CR123A batteries are being used.
Overheat Protection
The light will accumulate a lot of heat when working on High mode for extended periods. When
the light reaches a temperature of 65°C, the light will automatically step down a few lumens to
reduce the temperature. High mode can be reselected if needed.
Usage and Maintenance
Disassembling the sealed head can cause damage to the light and will void the warranty.
Replace the battery in time to ensure normal use for next time.
If the light will not be used for an extended period, remove the battery, or the light could be
damaged by electrolyte leakage or battery explosion.
