Patent attributes
A traffic signal system has a main housing unit that encloses three nested arrow signals pointed towards the top, namely, a red arrow signal, a yellow arrow signal nested within the red arrow signal, and a green arrow signal nested within the yellow arrow signal. Each arrow signal is made with a plurality of LEDs. A smaller satellite housing unit, preferably one-third to two-thirds the height, is attachable to the main housing unit to provide a left or right turn signal also comprised of three nested arrow signals. Arrow signals are preferably removably installed. A removable cover provides access to the back of the three arrow signals. Both housing units are preferably waterproof and have hinged closures. An electrical terminal block provides for electrical connections. Removable visors shade the light from the LEDs. Water drain knockouts to the visor and housing units facilitate water removal.
