Abstract
Abstract A lamp capsule and uses thereof in electrical receptacles, connectors and plugs for indicating circuit-energization and location in dark areas. The capsule consists of a lighttransmitting, tubular, dielectric, synthetic polymer capsule having an open end and a closed end encapsulating a small neon lamp having a pair of bare wires projecting from its base. One wire extends through an opening in the closed end of the capsule and the other wire is curvately bent at its end adjacent the base of the lamp and extends along the lamp and out the open end of the capsule.
