Coming up with ways to make you safer on the road, when using Serfas lights, is a top priority. NEW for 2016, 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.

George Cotsirilos –
At first, I was nervous buying a light for $50, but this thing just keeps going. It’s been about two weeks since I charged it and it’s still going STRONG. I ride my bike about 15 miles a day and it’s absolutely perfect for night riding. It lights up a dimly lit path fantastically well. I’d highly recommend getting one. I also like that it’s easily removable and customizable.

I like being seen and this light makes me seen, but the charge doesn’t last long. The light may hold a charge for 4-5 hrs on low flash. When on high flash charge will last 2-3 hrs if luck is on my side.
