An instrumentation gauge for a vehicle includes a single piece light guide divided into multiple sections by an opaque light guide insert. The single piece light guide includes at least one telltale graphic printed on a surface of the light guide in each of the light guide sections. When light is communicated into a given section of the light guide, the light scatters on the telltale graphic causing the graphic to be illuminated and distinguishable from a same or similar colored background.
