Abstract
Abstract The disclosure relates to a socket for a vehicle light bulb. The sides of the socket are cut or embossed to provide oppositely disposed J-slots having circumferentially extending portions for the seating of retaining pins on the light bulb. A cut or embossed slot is provided in the wall at one side, 90° from the J-slots, for orienting the bulb relative to the socket. The socket may be used as original equipment or as a replacement part for a damaged socket.
