When the car runs at high speed, that is, when the display quantity is greater, the display voltage of the power circuit 10 is low level, the brightness of the luminous element becomes low. Thus the light quantity of the entire indicator 7 is dependent on both the brightness level and display quantity, and becomes approximately constant in the displayed range. The brightness of the luminous element is regulated in the indicator 7 by changing the level of display voltage applied to the indicator.
