Sudden Stop helps driving
Believed to be able to prevent accidents from happening, the sudden stop device is fitted around the license plate, and when the car brakes the lights around in the sudden stop device flash at a high rate, which are guaranteed to wake up the driver behind.
Features:
Amazing flashing license plate frame
Uses ultra-bright LED technology
Attracts attention so tailing drivers can stop before it is too late.
Activated only when you slam on your brakes
1/4 second quicker reaction time at 60mph equals 20 feet of stopping distance.
Flashing brake lights significantly reduce driver reaction time and rear-end collisions
Not part of your car’s electrical or braking system so there are no wires to attach.
Priced at $29.99.
