“BLAST” Audible Low Battery Indicator
Coming up with ways to make you safer on the road, when using Serfas lights, is a top priority, our “BLAST” Audible Low Battery Indicator emits a loud 85 Decibel signal when your light battery gets under 10 minute runtime in that specific mode.
How It Works
- When the battery reaches 10 minutes of runtime, in its current mode, the light will emit a long beep followed immediately by a short beep. Sound will continue every minute.
- When the power button is pressed it will put the light in the next longest running mode & it will restart the battery low alert until 10 minutes of runtime in the mode is reached. Repeat as necessary. Example: Going from highest mode to lowest mode at first beep could extend runtime up to 5 times.*
- Light will emit beep sound repeatedly when last minute of runtime in the current mode is reached.
- While charging the light the power button will blink blue. When full charge is achieved light will beep to notify charging cycle is complete.
- Light emits a beep when power button is pushed & light goes from mode to mode.
