  • Patent number: 6682201
    Abstract: A dial for an indicating instrument, in particular in a motor vehicle. The dial comprises an optically conducting basic body whose outside is shaped as a two-stage cone. Except for light passages (10) forming symbols, the outside is covered by an opaque layer (9), the light, which hag previously been coupled into the basic body (2), exiting there. A special feature is that the basic body (2) is produced by injection molding, and this permits the production of a non-planar outer surface, the opaque layer (9) itself being produced on the outer surface.
