Abstract
Abstract The present invention relates to a vehicle warning system device that is capable of detecting sirens of approaching emergency vehicles. This device includes a plurality of siren detectors, each siren detector capable of generating status signal at an output of each siren detector when activated by a siren. A plurality of visual indicators and a speaker. A microprocessor having a microprocessor plurality of input, a microprocessor plurality of output and a microprocessor memory, the microprocessor plurality of input connected to each output of the plurality of siren detectors, the microprocessor plurality of output connected both to the speaker and an input of each of the plurality of visual indicators.
