The graphical element is adapted to be illuminated by the indicator light for indicating an active vehicle function as well as backlit by the backlight. A switch coupled to the backlight selectively turns OFF the backlight in response to a drive signal supplied by the indicator light. In this manner, the backlight is OFF when the graphical element is illuminated by the indicator light.
