Abstract

In an indicating instrument (1) with a translucent dial (8), an illuminated pointer (4) is arranged, out of the viewing direction of a viewer, behind the dial (8) on its rear, inner side (7). The surface of the outer side and/or of the inner side of the dial is reflection-reducing so as to enable the dial to serve the function of a covering glass.
