Abstract

An illuminated indicator gauge having a dial plate (12) and a pointer (18) each of a transparent or translucent material and formed with a reflecting surface wherein the rays of light from a light source (28) into the dial plate are conducted toward an outer end portion of the pointer after two reflections at the respective reflecting surfaces (22, 24) of the dial plate and the pointer whereby the pointer is caused to light up in the region of the outer end portion which is formed with a matte surface (26) at which the light rays are diffusely reflected, characterized by light condensing means (40, 12a) located between the light source and the reflecting surface (22) of the dial plate so that the light rays from the light source toward the reflecting surface of the dial plate are condensed before reaching the reflecting surface. The condensing means may be integral with the dial plate. <IMAGE>
