Claims (1)

[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 the light emitting element on and off according to the operation of the load; and a low potential of the illumination circuit and the light emitting element. and a potential raising means for raising the potential on the low potential side to a predetermined value when the illumination lamp is turned on, and causing the light emitting element to emit light 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 reduced when the illumination lamp is turned on. (2) The display circuit includes a first resistor connected to the low potential side of the light emitting element, and the potential increasing means connects the low potential side of the light emitting element to the first resistor.
The load operation display device for a vehicle according to claim 1, further comprising a diode and a second resistor connected between the connection point of the resistor and the lighting circuit.
