ABSTRACT:
The invention relates to a combined instrument including a printed board, on which a light source is provided that generates light for illuminating a display, and including a frame, inside of which the printed board is accommodated. The display field is directly mounted on the printed board and a light guide is provided, which is accommodated inside the frame in an area adjoining the printed board. The light guide is arranged in such a manner that light emitted by the light source is fed into the light guide and radiated onto the display field.
