ABSTRACT:
Components of a lighting system, exemplified by the lighting system utilized in commercial transport vehicles are protectively housed in a receptacle apparatus comprising an enclosure body, open at one side, a closure or cover member arranged to extend into the open side of the enclosure body and O-ring sealing means, retained in an annular channel in the enclosure body, for detachably securing the enclosure body and closure member in sealed relationship. The closure member is constructed at one end with an outer tapered cylindrical flange, a portion of which is located in abutting relation to a circular end wall extending around the open side of the enclosure body. This arrangement defines a prying aperture in which a tool such as a screw driver may be inserted to pry off the closure member when desired.
The closure member is characterized by a tubular extension formed integrally with the tapered cylindrical flange and arranged to project inwardly through the opening in the enclosure body in predetermined spaced relation thereto. The tubular extension is further characterized by an extended annular sealing area and a retaining shoulder which is operable to compressibly force the O-ring in displaced relationship along the extended sealing area when the tubular extension and enclosure are in the predetermined spaced relationship noted.
