The electrical contacts on these bulbs are the same wires that extend into the bulb. The wires are bent up onto the sides of the bulb's glass base, where they make contact with the socket, which is narrower at the bottom than at the opening, giving it a wedge shape - usually ensuring a tight connection. The bulb is inserted and removed with straight in or out force, with no turning.
T represents tubular bulb shape; number after the dash is bulb diameter in millimeters
