Abstract

A lamp monitor for a bus or other motor vehicle has a processor, a current sensor, a memory and a display for monitoring the current through the lamps. In program mode, the processor samples the current passing through the warming lamps and calculates an operating range. In operate mode, if the current sensor detects current passing through the lamp within the operating range, then a status lamp, located near the driver of the bus or motor vehicle, is illuminated.
