The present invention relates to illumination of an instrument for displaying information. In particular the invention relates to illumination for an instrument suitable for use in a vehicle. Such instruments, located on the dashboard of an automotive vehicle, require illumination to allow the driver to read the information when it is dark. An instrument suitable for use in a vehicle is thus provided, generally comprising a housing, an information bearing surface, a transparent protective cover having an interior surface and an exterior surface, and a first light source coupled to the protective cover. The protective cover acts as a light guide and is arranged to allow light to escape at a selected location into the interior of the instrument to illuminate a portion of the information bearing surface.
