Abstract:
1. An instrument for a vehicle that includes a light source whose lighting up/off is switched based on an input of vehicle information, and control means that controls the light source so as to perform a directing operation regardless of the input of the vehicle information, based on a manipulation state of a power supply switch, comprising: an input circuit which receives the vehicle information as an electric signal, and includes a resistor connected to the light source related to the vehicle information; an electric potential adjustment circuit that adjusts a potential of a line of wiring between the light source and the input circuit, based on a control signal from the control means, and invalidates an effect on the light source from the vehicle information; and a light source control circuit that performs a directing operation by controlling the lighting up/off of the light source, based on a control signal from the control means, when the effect on the light source is invalidated by the electric potential adjustment circuit.
