CATEYE - Rapid X2 Kinetic USB Rechargeable LED Bike Safety Tail Light

It's time for road safety to run 'round the clock. The CatEye Rapid X2 Kinetic is a 50-lumen, USB rechargeable bicycle safety light that mounts easily on your seatpost. A built-in accelerometer automatically switches into a constant burst mode when it senses a sudden change in speed. Similar to daytime running lights on an automobile, the Rapid X2 Kinetic helps make your presence known as a cyclist. 180 degrees of visibility allows you to be seen from varied perspectives. A Battery Auto-Save feature makes sure you're covered the entire ride by automatically switching to a flashing mode should the battery run low. With up to 30 hours of runtime, the Rapid X2 Kinetic ensures you'll be drained from your ride long before your light is.
