Abstract
A lamp assembly having a plastic housing and a plastic lens is molded in a rotary transfer molding machine having upper and lower mateable housing dies and upper and lower mateable lens dies in which the housing and the lens are molded simultaneously. The machine is then indexed so that the upper housing die with the molded housing retained in it is mated with the lower lens die with the molded lens retained in it. These two dies are configured so that an annular seal bead cavity is formed at an interface of the dies. A seal bead is then molded to join the molded housing to the molded lens to provide the lamp assembly. The machine is then indexed again so that the upper housing die with the lamp assembly retained in it is mated with an overlay die and a decorative overlay is molded on the peripheral margin of the lens.
