A housing for a circuit includes a top wall that defines an aperture configured for receiving a fastener, and a bottom wall integrally formed with the top wall, positioned directly below the aperture in a height direction, and extended across the aperture with respect to the height direction. The circuit is mounted on a bottom side of the bottom wall. The top wall and the bottom wall define an interior of the housing, and cooperate to obstruct egress of debris from the interior of the housing to the circuit at the bottom side of the bottom wall.

An aircraft passenger cabin light. The light has: an elongated shape having a longitudinal direction (L) comprises: a cabin wall illumination assembly, which extends along the longitudinal direction (L) of the aircraft passenger cabin light and which is configured for illuminating a portion of a wall of an aircraft passenger cabin; and a plurality of personal reading light units for providing personal reading light illumination to passengers. The plurality of personal reading light units are arranged in an array extending along the longitudinal direction (L) of the aircraft passenger cabin light Said array is arranged along the cabin wall illumination assembly.

An illumination device for an interior space of a vehicle includes at least one light source and at least one light surface. The light surface is formed by at least one at least partially mirrored optical fiber, and the optical fiber can be adjusted to a shape of a windscreen.

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.
