An adhesively sealed beam lamp unit including a lens and reflector having cooperating and opposing step-shaped 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 innermost pair of opposing steps. Additionally, reservoirs, located on either side of the sealing surfaces, restrict excess adhesive from spreading onto areas affecting lamp unit optical performance or outer dimensions.
