Abstract
An analog indicator for an automotive vehicle is provided. This indicator includes a self-luminescent indicating pointer and a dial plate on which a fluorescent layer is formed. When an input signal indicative of a indicating parameter is changed, the pointer radiates an ultraviolet ray onto the fluorescent layer on the dial plate so that it glows. An observer can thus visually identify a value indicated by the pointer or displacement of the pointer.
