A method and apparatus include attaching a lighted cup holder to a seating arrangement. The lighted cup holder includes a cup holder body and a light-producing light source, with the cup holder body being attached to the seating arrangement and having a cup receptacle therein, the light-producing source being disposed within the cup receptacle for illuminating the receptacle. A light-sensitive element operatively connected to the light source selectively controls production of light by the light source in such a manner that illumination of the cup holder is provided only under conditions where visibility is reduced to the point that it becomes difficult to locate the cup holder. The light-sensitive element is mounted on a master lighted cup holder and controls illumination of the master lighted cup holder and one or more slave lighted cup holders operatively connected to the master lighted cup holder.
