ABSTRACT:
An indicator for displaying either low liquid level or satisfactory liquid level conditions within a tank includes a sensor for detecting the liquid level conditions, a photodetector for detecting an ambient dark condition, a pair of indicator lights for indicating either the low liquid level or satisfactory liquid level conditions, and electrical circuitry operable to illuminate one of the indicator lights upon detection of the ambient dark condition by the photodetector and detection of either the low liquid level condition or satisfactory liquid level condition by the sensor.
