Abstract
A headlamp assembly comprising a reflector defining an open front end, a lens adapted to close the open front end of the reflector to form a lamp chamber, a bulb mounted in the lamp chamber, and a mounting structure. The reflector and lens define respective annular flange portions which are seated together at an interface and the mounting structure is formed as an injection molding including an annular main body housing portion surrounding the reflector and an annular seal portion at the inner periphery of the main body portion encapsulating the seated together flange portions so as to seal the interface between the flange portions and seal the lamp chamber. Sealing of the lamp chamber is further facilitated by the provision of a series of annular grooves in the reflector flange portion and a series of annular ribs in the lens flange portion sized to fit in the respective annular grooves in the reflector flange portion.
