Abstract

An electric lamp including an insulative (e.g., plastic) base, an envelope located within the base and having a filament therein and a pair of conductors (e.g., nickel-iron alloy wires) projecting externally from the envelope, passing through the base and extending therefrom. Each conductor includes means (e.g., knurls) formed therein for removing undesirable surface material (e.g., oxide) from a respective contact located within a socket in which the lamp is positioned. Such removal, achieved during lamp insertion and eventual withdrawal, thus assures a sound electrical connection between the 'cleaned' contact and a second lamp designed to replace the original. These features are particularly advantageous in the automotive field, especially that portion of the field involving taillight and similar assemblies.
