Abstract:
A signaling device for signaling a public transportation driver for installation in a transit site, comprising:an activation unit, containing a switch, timing circuit for energizing a light emitting diode via an intermittent pulsing lighting circuit, said intermittent pulsing lighting circuit for alternately activating and deactivating said light emitting diode for a selected period of time, and electronics for controlling electricity to a light emitting diode; a replaceable power unit which includes one or more batteries, for supplying power to said activation unit and a signal unit and said light emitting diode; and said signal unit including said light emitting diode positioned to point at an approaching transit driver to signal the presence of a passenger, which is powered by said replaceable power unit, and controlled by said activation unit; wherein said signaling device is configured for installation in a tubular post member, and when said switch in said control unit is activated by a passenger, said light emitting diode in said signal unit blinks at a rate determined by said intermittent pulsing lighting, for a period of time determined by said timing circuit.
