Abstract
The present invention is a meaningful traffic light for motor vehicles. By flashing light(s) of colours orange, green or red, it indicates one predetermined unit variation in speed or in frequency of pulses received from speed sensor of the vehicle on which the traffic light is installed. Also, different configurations of said lights symbolise stationary state, or different levels of speed of the vehicle. When difference between the current speed and the speed at which the latest flashing happens is equal or greater than one unit, a flash of a light arises. (A)
