The invention relates to automobile sealed-beam headlamps in which a reflector and lens assembly are hermetically sealed by an epoxy resin. A pressure relief hole in the reflector eliminates the problem of excessive expansion and contraction of the atmosphere within the lamp such as would prevent forming a hermetic seal between the reflector and lens during the epoxy resin curing cycle. A deformable metal pellet forms a hermetic seal in the pressure relief hole. An epoxy resin is applied over the deformable metal seal and cured to produce a final permanent seal.
