A gauge is disclosed which provides both an analog indication of a variable quantity and a warning light signal when a danger point is indicated. The face of the gauge includes a slot through which a warning light shines when the danger point is indicated. The slot is located in the vicinity where a conventional pointer would indicate the danger point. Instead of having a conventional slender pointer attached to and rotating on a pinion shaft of a gauge movement, the gauge of the present invention has attached to the pinion shaft a screen in the form of a sector of a circle. The screen subtends an angle at least equal to the entire range of the variable. One edge of the screen is suitably marked as a narrow pointer.
