Coming up with ways to make you safer on the road, when using Serfas lights, is a top priority. Their "BLAST" Audible Warning System 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.
