A glass incandescent display lamp is provided which includes a glass container and a glass faceplate forming a sealed glass envelope enclosing an evacuated space. A plurality of electrically-conductive filament posts having first and second ends is provided with the filament posts extending through a wall of the glass envelope so that the first ends terminate in the evacuated space, and the second ends terminate outside of the sealed glass envelope. A set of incandescent filaments is secured to the first ends of the filament posts for the passage of current and for producing a display. In addition, a plurality of conductor pins for connecting the filaments to an external source of power is provided with each of the conductor pins having one end embedded in the wall of the glass envelope and the other end extending to the exterior of the sealed glass envelope. In order to provide strain relief for the filament posts and in order to prevent breaking of the hermetic seal, the second ends of the filament posts are connected to the portion of the conductor pins which are outside of the sealed glass envelope.
