ABSTRACT:
A transparent pointer for an indicating instrument has a light receiving surface centered on the axis of rotation of the pointer and a light bulb is positioned on the axis adjacent the light receiving surface to brightly illuminate the pointer at the same brightness for all pointer positions. A gage mechanism drives the pointer through a pointer support which is in part laterally offset from the axis to permit bulb location on the axis.
