Abstract
An adhesively sealed beam lamp unit including a lens and reflector preferably having substantially rectangular peripheries and cooperating and opposing sealing surfaces located approximately about the lens and reflector peripheries. Contact between the lens and reflector sealing surfaces is limited to one or more portions along the sides thereof. Additionally reservoirs, located adjacent to the sealing surfaces restrict excess adhesive from spreading onto areas affecting lamp unit optical performance, outer dimensions, and integrity.
