Abstract

A vehicle signaling display device to be mounted on an automotive vehicle, so that signaling lights of the device are visible for drivers of following vehicles, includes orange or amber, red and green lights and includes a system specifically designed to count speed sensor pulses for measuring speed of any vehicle of any make and model on which the device is installed, for controlling the signaling lights in accordance with the speed of the vehicle and regardless of operation and position of accelerator pedal of the vehicle, in order to perform a set of standardized operations of the signaling lights for dynamically preventing traffic crashes.
The device (a) turns on a distinct arrangement of a number of lights of the signaling lights for indicating different ranges of the speed of the vehicle so that a red light of the signaling lights remains lit without flashing regardless of braking as advanced stop sign indicating very low speed or stationary state of the vehicle, orange lights of the signaling lights remain lit indicating low speed of the vehicle and green lights remain lit indicating forward motion with constant speed; (b)flashes orange lights whenever the speed of the vehicle is reduced by a standardized value without braking;
(c)flashes red lights whenever the speed of the vehicle is reduced by the standardized value by braking; (d) flashes green lights to indicate acceleration by the standardized value; so that as the rate of deceleration increases, the red or orange lights flash faster.
