示装置。[Claims for Utility Model Registration] (1) A vehicle having a load circuit that connects a power source and a load and at least controls on/off of the load, and a lighting circuit that connects the power source to a lighting lamp and controls the lighting lamp on/off. a display circuit that is connected to the load circuit and has a light emitting element that emits light according to the operation of the load, and controls an input current of the light emitting element;
a shunt means connected in parallel to the illumination lamp to shunt the input current of the light emitting element when the illumination lamp is turned on, causing the light emitting element to emit light and turning on the illumination lamp according to the operating state of the load; A load operation display device for a vehicle, characterized in that the output light amount of the light emitting element is sometimes reduced. (2) The display circuit includes a first resistor connected to the input side of the light emitting element, and the shunting means connects the input side of the light emitting element and the first resistor to the lighting circuit. A utility model characterized in that the utility model comprises: a second resistor connected between the two resistors; and a transistor that is interposed between the second resistor and the lighting circuit and becomes conductive when the lighting lamp is turned on. A load operation display device for a vehicle according to claim 1.
