Horn and alarm - mandatory equipment
According to the norms for the admission of vehicles to operation, each car must be equipped with a sound signal. The alarm system is designed so that in an emergency the driver can warn other road users about the forced stop. Since the alarm must work even when the ignition is off, the alarm switch is powered directly from the battery through the fuse. Direction indicators, on the contrary, receive voltage through the ignition switch only when the ignition is on. Signaling devices should always be checked before riding.
