Abstract

A plug in lamp with spring side contacts having bulb, holder, lugs, and a seal is disclosed. The lugs have outwardly arced spring sections that are compressed during lamp insertion, thereby forming a latching mechanism to hold the lugs and lamp in place, while simultaneously providing electric power through the lugs. Sealing structures are disclosed that protect the welds, and others electrical features from environmental degradation.
