Coming up with ways to make you safer on the road when using Serfas lights is a top priority.  The Serfas Thunderblast bike headlight features a “BLAST” Audible Low Battery Indicator that 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.
