ABSTRACT:
An all glass sealed beam headlamp unit is disclosed having polygon shaped lens and reflector members which is capable of being alternately sealed together with an adhesive as well as being fusion sealed by reason of the sealing rim construction being employed. Specifically, the cooperating and opposing sealing rim surfaces of both members include planar sealing surfaces located at the outer periphery which extend longitudinally without interruption around all sides of said members along with rib elements projecting forwardly from the planar sealing surface at all corners of the lens member with said rib elements being located at the inner periphery of said lens member for physical abutment with inner edge of the planar sealing surface located on the reflector member at the corner locations.
