Abstract
A multicolor function indicator light system is provided for an audio amplifier or similar electronic equipment. A sensor circuit monitors operation of the equipment. An indicator light device has a plurality of different color outputs. A control logic circuit receives input signals from the sensor and controls the indicator light device so that different sensed modes of operation of the electronic equipment are indicated by different color outputs of the indicator light device
