Serfas' Orion Blast Rear Light with AWS features amber secondary lighting, 70 micro LEDs, and a clever low battery indicator system that beeps when the battery is low. When the battery reaches 10 minutes of runtime in its current mode, it emits a loud 85-decibel signal -- a long beep immediately followed by a short beep -- every minute until it dies or the mode is changed by pressing the power button. Upon doing so, the light will switch into the next longest running mode in order to preserve battery life while maintaining illumination. When only a minute of battery power remains, the light will emit a repeated beeping sound until it turns off or is charged. While charging, the power button will blink blue. When charging has completed, the light beeps to indicate its ready.
