A multiplexed lamp assembly is adapted to be coupled to a source of an alternating current signal, and includes a control unit, and first, second, third and fourth lamp units. The control unit has an input side adapted to be coupled to the source, and an output side with a control line unit. The control unit receives the alternating current signal, and is operable so as to generate first, second, third and fourth control signals at the control line unit. Each of the first, second, third and fourth control signals is generated during a respective one of first, second, third and fourth quadrants of a cycle of the alternating current signal. The first, second, third and fourth lamp units are coupled to the control line unit and are adapted to be coupled to the source. Each of the first, second, third and fourth lamp units is activated by a respective one of the first, second, third and fourth control signals so as to allow current flow from the source therethrough and emit light during a respective one of the first, second, third and fourth quadrants of the alternating current signal.
