Abstract
A knob assembly includes a repositionable knob having an outer surface and an inner surface defining an interior, light-transmissive indicia provided on the knob and viewable from the outer surface, at least one light source located relative to the repositionable knob and emitting light into the interior of the knob to backlight the light-transmissive indicia, a position sensor providing a position output indicative of the position of the repositionable knob, and a controller configured to receive the position output and control the at least one light source to maintain a predetermined backlighting of the indicia.
