Abstract
Methods and systems are provided for operating a lighting array that is comprised of one or more lighting segments. In one example, the lighting segments may be comprised of light emitting diodes that are electrically coupled in series. The lighting segments may be controlled responsive to output of a potentiometer and the lighting segments may be controlled responsive to positions of circuit boards in an enclosure.
