Abstract
In an indicating instrument, especially in a motor vehicle, having a cover glass (4) that appears dark and, under incident light, prevents any view of a dial (3) arranged at a distance behind it, and having at least one light source (8) arranged behind the dial (3) to transilluminate said dial (3) and therefore render the dial (3) visible through the cover glass (4). In order to prevent the dial (3) becoming visible when there is only incident light, the transmission of the dial (3) is matched to the transmission of the cover glass (4). To this end, in particular, the dial (3) is provided with a low transmission.
