Abstract
A warning module for use with a motor vehicle having multiple sensor inputs and multiple sensor outputs. The inputs are coupled to sensing circuits for monitoring a condition such as engine temperature. The outputs are coupled to one or more light bulbs or other visual indicators which are activated at a lamp flash frequency. A variable frequency oscillator activates an audible output device, preferably a piezo-electric buzzer. The light output levels are diminished for nighttime use. A plastic housing supports a piezo-electric transducer and reverberation plate and achieves a high sound output.
