The QuietKat Smart Tail-Light senses your speed and automatically gets brighter as you decelerate, acting as a brake light. This small USB rechargeable light straps to the rear rack or seatpost of the bicycle. It provides safety in low light situations and alerts other riders or traffic of your changing speeds. Choose from three modes; High, Low, and Strobe.
