Three Generations of Grooveback, left is the original GE, equipped with Ecolux “Honeycomb” LEDS, Econolite bought the stoplight division from GE and modified the same molds with their own name, center. Equipped with original glass reflectors and glass “brick pattern” lenses (these were also available with “sawtooth pattern” lenses). On the right is the final version, the short groove- the vertical grooves in the back didn’t line up well all the time letting water in, so it was modified so the grooves didn’t go all the way to each section. Equipped with GE RX11 LEDs.
