ABSTRACT:
A movable pointer includes an elongated, translucent substrate having an EL lamp covering one side of the substrate. The pointer emits light from an adjoining, narrower, front side which is roughened slightly. The ends of the substrate are capped or coated to prevent light emission. A second EL lamp can be attached to a second side of the substrate. The width of the EL lamp can be tapered to provide a pointer which is brighter at one end than at the other. Electrical connection to the EL lamp is made with a compliant ribbon having conductive stripes on one or both sides thereof. The ribbon is mechanically and electrically attached to contacts on the EL lamp.
