A flashlight bulb of the type having a sealed envelope from which two pins extend in parallel relationship can be removably mounted in a PR-type base by the use of an insert that fits within the PR-type base and that includes, in addition to the holes for the pins, balls that are urged laterally against the pins by compression springs within the insert. The balls establish electrical contact with the pins and are connected by conductors to the terminals of the PR-type base.
