ABSTRACT:
The present invention relates to an early warning braking system whereby drivers are provided with the greatest opportunity to avoid a collision. This is accomplished by placing one or more photo sensor switches inside a vehicle to monitoring a driver's foot motion. The beam from the photo sensor switch is positioned in the path that the driver's foot would have to travel to apply the brakes. When the braking process occurs, the driver's foot breaks an optical beam (optical circuit), which is detected by a sensor. The sensor then triggers a relay switched that illuminates the brake lights, before engagement with the brake pedal, thereby illuminating the brake lights a moment in time before they would normally be illuminated. At 60 miles per hour this could give a driver an additional 22 to 88 extra feet of breaking distance.
