ABSTRACT:
A combination gauge for indicating a measured condition, such as battery condition or coolant system temperature, which provides both a visual light means and a numerical or other calibrated indicator gauge, providing when a special pre-set condition occurs, the user is informed not only by the calibrated gauge but also by energization of the visual light means which illuminates the visible face of the gauge itself. The gauge is particularly useful for vehicle use, or other uses in which the user's attention is not likely to be on the gauge with any high degree of continuity, and yet the condition being sensed or monitored is such that it has rather critical limits.
