Abstract: A lamp assembly has a holder having a cup-shaped seat having an inner surface and a backwardly directed end and a socket engageable in the seat. This socket is formed with a forwardly open recess adapted to fit around a base of a bulb, an outer surface, a rear end formed with a flange having a forwardly directed face confronting the holder back end, an annular compartment formed in the rear end, a forwardly open front passage opening into the compartment, and a rearwardly open back passage opening into the compartment. Thus a fluid, water or moisture-laden air, can pass from inside the assembly through the front passage, then through the compartment, and finally through the back passage to outside the assembly. Contacts extending through the socket have outer ends adapted to be connected to wiring and inner ends exposed in the recess and engageable with a bulb therein. Formations between the socket and the holder retain same together.

Abstract: A socket adapted to fit through a hole in a panel and serving to hold a light bulb and connect same to a multiconductor plug comprises a one-piece L-shaped housing formed of dielectric material and having a generally circular-section tubular socket leg and a tubular contact leg. The legs are centered on respective axes and completely laterally imperforate and closed and together they form a continuous L-shaped passage. A dielectric insert sleeve snugly received in the socket leg is provided with formations complementary to a base of a bulb to be mounted in the socket. A dielectric plug fitted in and completely blocking the contact leg is formed with a pair of adjacent throughgoing slits receiving respective conductive contacts strips each having an outer end exposed outside the plug in the contact leg and inner ends projecting into the socket leg and engageable with the base of the bulb therein.
