ABSTRACT:
A boat light is especially adapted to be mounted upon the transom or stern of a cabin cruiser, speedboat, small yacht, or the like. A holder for a lamp unit has a spherically curved outer surface engaging a complementary inner surface of a housing attachable to the hull of the boat. The holder is universally adjustable to selected angular positions of adjustment relative to the housing. In a typical adjustment, the beam of the lamp unit may be projected horizontally despite the inclination of the transom from the vertical. In the selected position of adjustment, the tightening of screws by which the device is assembled and mounted on the transom is effective to preserve the lamp unit holder adjustment. This occurs when a shield closing the inner end of the housing is caused to bear against a rearwardly projecting surface of the holder. The holder, or at least the shield-engaging surface thereof, is of a deformable material. The shield, when the screws are tightened, deforms and flattens the holder material to bind the holder frictionally against the shield, thus to preserve the selected adjustment.
