Coming up with ways to make you safer on the road, when using Serfas lights, is a top priority. The "BLAST" audible warning system emits a loud 85 decibel signal when your light batter gets under 10-minute runtime in that specific mode.

- When the battery reaches 10 minutes of run time 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 and 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 run time 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 cycles is complete.
- Light emits a beep when power button is pushed and light goes from mode to mode.
