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