Abstract
An illuminated annunciator as in a gear selector has gear designation letters always lit and a ring around each letter selectively lit to indicate the active gear range. A generally conical light pipe with a conical central cavity has at one end an annular emitting surface adjacent the ring and at the other end it is illuminated by an LED. Another LED within the conical cavity illuminates the letter directly as well as via reflection from the wall of the cavity.
