Abstract
A threshold lighting system for recreation vehicles and the like. The system includes a threshold with a first light cavity extending along one side of the threshold for emitting light inwardly into a recreational vehicle in a first direction generally parallel to the vehicle floor, and a second light cavity on the opposite side of the threshold for emitting light in a second direction down the stairs leading to the threshold. The light cavities are preferably part of an extrusion forming the threshold, and the threshold is typically part of a door frame assembly provided as a unit.
