A graphic display is provided which is suitable for use in an instrument panel of an automobile. The graphic display includes a display lens and a number of backlit buttons which are formed by a unitary optically-conductive member, wherein both the display lens and the backlit buttons are illuminated by a single illuminated display located behind the unitary member. As such, the unitary member eliminates the requirement for a separately formed lens and buttons. Furthermore, the illuminated display generates graphics for both the display lens and the buttons, eliminating the requirement for insignia formed in the surface of the buttons and lights or light pipes behind the buttons for backlighting the buttons.

An illuminated apparatus comprises a fixedly mounted air core gage having a spindle which rotates in response to signals provided to the air core gage, a first coil fixably mounted with respect to the air core gage having a first axis coaxial with the spindle, a power source coupled to the first coil, providing power to the first coil, which responsively generates a magnetic flux, a pointer body mounted to the spindle and rotating in response to rotation of the gage spindle, a second coil mounted to the pointer body adjacent to the primary coil, a light source mounted on the pointer body, coupled to and receiving the electric current from the second coil, the electric current illuminating the light source, and a light pipe pointer arm receiving light from the light source and emitting light out of an exit surface to appear as an illuminated pointer to an observer.
