Serfas 100 LMN Thunderblast Audible

When using Serfas headlights, the top priority is to find ways to make you safer on the road. New for 2016, our "Blast" Audible Warning System emits an 85-decibel loud signal when your battery has less than 10 minutes of runtime in the current mode.

How does it work? When the battery reaches a runtime of just 10 minutes, the light emits a long beep followed by a short beep in the current mode. The sound repeats every minute. If the power button is pressed, the light switches to the next runtime mode, and the warning cycle is repeated. Repeat this as needed. For example, if you switch from the highest mode to the lowest mode at the first warning signal, the runtime can be extended up to five times.

During the charging process, the power button blinks blue. When full charge is reached, a beep sounds to confirm the charging cycle. The light emits a beep when the operation switch is pressed and the light switches from mode to mode.
