Abstract: An electrical connector comprises as shown in FIGS. 23 to 25, an insulating housing defining a socket for an electrical lamp bulb and first and second cavities and for receiving a first terminal and a second terminal respectively. The first terminal has a contact spring in the socket, the second terminal having a contact spring in the socket. An electric lamp bulb can be inserted into the socket so that contacts of the bulb are resiliently engaged by the respective contact springs. Each terminal also has a slotted plate portion for connection to an insulated electrical lead. The top wall of the housing is formed with two spaced holes for receiving lead wires of a diode. The first terminal has, a spring socket aligned with each of the holes and. Between the spring sockets, the first terminal has a reduced cross section severable portion, which is accessible to be sheared by shearing tooling, by way of an opening in the top wall and an opening in the opposite wall of the housing.
