It is a proven fact that motorcycles can decelerate more rapidly than most cars and trucks.The combination of a motorcycle's narrow profile and the brisk change in velocity during braking is the most common cause of rear end accidents involving motorcycles, and often the results are fatal to the rider. The TailMate™ by Fisher Instruments, is designed to enhance the reaction time of the driver of the vehicle behind when a motorcycle they are following begins to decelerate.Alert Those Behind You When Slowing Or Stopping In Traffic!!! TailMate™ State-of-the-Art solid-state electronic module converts your ordinary centre brake light or 3rd brake light into a visual alert when you are braking.With the TailMate™ installed, when you apply your brakes, it causes your brake light to automatically flash approximately 6 times before entering the steady-state ON red light condition.IF THE BRAKE IS APPLIED AGAIN WITHIN THE NEXT 20 SECONDS, THE BRAKE LIGHT OPERATES NORMALLY TO AVOID FLASHING CONSTANTLY IN STOP-GO TRAFFIC.
