ABSTRACT:
An illuminated pointer for an instrument includes an arm section for indicating a display parameter on the instrument, a tail section, and a bridge section extending between the tail section and the arm section. The tail section is configured to focus light received from a light source through the bridge section and into the arm section to more evenly illuminate and/or enhance the brightness of the arm section.
