Abstract
A vehicle lamp has a plastic lamp body (10) with a sealing leg (16) that extends from the back of the lamp body and is pressure-welded and held on a vehicle body panel (18), via an elastic sealing material (20). The elastic sealing material is formed by injection-molding of a thermoplastic foamable elastomer where the lamp body (10) is inserted into a mold (40A) and the sealing leg (16) is projected into a sealing-material molding cavity (C1). The sealing material is molded over the whole area of the sealing leg and has a transverse cross section that is U-shaped.
