Pulse is a proven, cost effective rear-end collision avoidance system that can measurably reduce the risk of being rear-ended.  Pulse is a small electronic device which connects to the wiring for the OEM third brake light.  When you step on the brake pedal, Pulse causes the 3rd brake light to pulse 4 times.  With Pulse, distracted drivers are 69% more likely to notice you braking and the reaction time of the vehicle behind you is improved by almost 50%. Risk rating improvements can translate to lower insurance rates.
