A multi-function electronic warning horn system comprises a couple of horns (1, 2) and a microprocessor (6), integrated in an electronic module (16) comprising a voltage adjuster (13), an oscillator (17), power stages (3, 4) and a control circuit (7). Horns (1, 2) are controlled by either the push-button (5) of the steering wheel for the traditional function of acoustic signaling or by a coded signal transmitted to microprocessor (6) by the "intelligent" electronic unit or onboard computer of the vehicle for the function of buzzer.
