The first metal contact comprises an arched portion, which is received by and protrudes through the central opening in the top wall of the socket shell to make electrical contact with the tip contact of a lamp bulb. The first metal contact further comprises: (1) a triangular portion for piercing the insulator of the electrical wire to make electrical contact with one of the conductors of the electrical wire; and (2) a rectangular mounting portion, which is received by a cavity in the socket shell, thereby firmly retaining the first metal contact with respect to the socket shell.
