With a built in accelerometer, this light automatically turns on Hi for an ultra visible 2.5 second burst when it detects bike deceleration. Rear visibility isn't the only safety factor when on the road. Side visibility is often overlooked yet is equally as important when taking to the pedals. The USB Rechargeable Rapid X2 Kinetic provides a bright, powerful glow with incredible side visibility up to 50 lumens. When the battery runs low, the low battery "Auto Save" function automatically changes the light pattern from the current mode to flashing, providing an additional hour of riding safety.
