Abstract:
     A surface mountable miniature incandescent lamp assembly has an elongated substantially cylindrical glass envelope wherein a filament is contained in contact with metal members and filament is contained in contact with metal members and having glass-to-metal seals with the glass envelope. A substantial portion of the outer surface of the glass envelope is coated with a light reflective metal coating, with a non-coated elongated window transparent to light being left on the surface. The metal members and extend axially to the outside from the envelope and when mounted to a circuit board provide electric contact for the lamp. At least of the end members includes a unique surface feature, such as a flat portion of an otherwise cylindrical surface, which is directionally coupled relative to the window of the glass envelope and which acts as a key or indexing surface for mounting the lamp assembly to the receiving surface (circuit board) with the window disposed in the desired direction.
