ABSTRACT:
A vehicle lamp assembly has an opaque housing portion and a light transmissive lens portion. The housing includes a peripheral channel for accepting a sealing adhesive and a complementary peripheral tongue on the lens portion. The bottom of the channel is characterized by a plurality of energy directors which contact the tongue and are locally upset by a ultrasonic weld apparatus to provide local welding between the lens and housing. The local welding provides fixtureless retention of the respective parts during the curing of the sealing adhesive.
