摘要

Electrical, optical and acoustic device, to denounce during the driving examinations, the interventions of the instructor, characterized by the fact that it consists of a pilot light of red color, arranged on the dashboard by means of a suitably screwed support, on which another green pilot light is installed, which stays on while the device is connected, which is carried out by acting on a switch located with the support itself, the red light being the optical signal that accuses any intervention on the pedals of the double command, for the clutch and brake, while the acoustic signal is emitted simultaneously by a buzzer, connected between the red light supply point and the mass of the vehicle.
