Green light (traffic signal) countdown device

摘要

An attachment for a standard traffic light assembly functioning as a precise, real-time, numerically displayed countdown warning device indicating the exact-moment of change from the green to the amber signal. The device will be parallel and visually in-line with the green signal light. A lighted frontal viewing surface will display in sequence the numerals five (5) through one (1) in descending order for a numbered countdown of luminous green light as follows; 5 . . . 4 . . . 3 . . . 2 . . . 1. A blank screen will then coincide simultaneously with the lighting of the amber signal.
