First Claim
Patent Images
1. A progressive slow/stop signaling system for installation on a vehicle to warn the driver of a following vehicle of an impending change in the speed of the vehicle:
- a group of six or more lamps mounted at the rear of the vehicle, a first switching device actuated by movement of the accelerator pedal, a second switching device actuated by movement of the brake pedal, the first switching device actuated by progressive movement of the accelerator pedal to decrease the speed of the vehicle controlling the progressive energization of a first portion of said group of lamps, such that an increasing number of said first portion of said group of lamps is energized with progressive movement of the accelerator pedal, the second switching device actuated by movement of the brake pedal to increase braking controlling the progressive energization of a second portion of said group of lamps, such that an increasing number of said second portion of said group of lamps is energized with the progressive movement of the brake pedal, thereby alerting a following driver to an impending change in the speed of the vehicle.

8. A progressive slow/stop signaling system for installation on a vehicle to warn the driver of a following vehicle of an impending change in the speed of the vehicle:
-
a group of six or more lamps mounted at the rear of the vehicle, an electronic sensing circuit for providing an electrical output signal representing the position of the throttle and accelerator pedal of the vehicle, a pressure sensitive device for providing an electrical output signal representing the pressure applied to the brake fluid by the master cylinder of the vehicle, an electronic control circuit, said electronic control circuit controlling progressive energization of a first portion of said group of lamps, in response to the electrical output signal from said electronic sensing circuit indicating progressive movement of the accelerator pedal, said electronic control circuit controlling progressive energization of a second portion of said group of lamps, in response to the electrical output signal of said pressure sensitive device indicating progressive movement of the brake pedal, thereby alerting a following driver to an impending change in the speed of the vehicle. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
