Abstract: A control for multiple circuit illumination lamp panels includes a group of electroluminescent panel segments including a first set of electroluminescent panel segments unique to a function mode and at least one second set of electroluminescent segments associated with at least one common indicia for at least two functional modes in combining first and second sets related to a functional to form a mode group. The sum of the areas of each mode group is then equalized to provide consistent illumination intensity and coloring regardless of the functional mode selected for the radio. Sizing of the segments can be provided by enhancing conductive areas aligned with, adjacent to or remote from the conductive areas aligned with indicia on the bezel and on the actuators on the bezel. The balancing of illumination intensity can also be incorporated in multiple electroluminescent panels so that a single switching power supply can be utilized with several audio system bezel designs having different functional modes.
