The S1500 is the next generation of lighter, brighter flashlights from Mountain Lab. In addition to regular flashlight modes, the S1500 also features 'Smart Mode'—an extra safety feature for riders in daylight. In Smart Mode, the S1500 emits a bright strobe light to increase rider visibility and safety. When daylight fades, the flashlight automatically switches to a steady headlight. In Smart Mode, after two minutes without motion the light will turn off to preserve battery life, until motion is detected again. The S1500 also features a lockout mode that can be used to prevent the flashlight from accidentally turning on when carried inside a backpack or pocket. The S1500 Flashlight kit includes both handlebar and helmet quick-connect mounting options.
