Abstract
A lamp base locking clip including a plate having a lip extending outwardly on one end, and a flat portion on the opposite end, is captured in a keyway formed in the glass neck of a lamp body. One of the lamp lead-in wires is welded to the flat portion of the clip and a rim on a lamp base shell is welded to the outwardly extending lip, thus forming a lamp-base assembly with good torque resistance and no lead-based solder.
