Abstract
A vehicle lamp assembly includes a housing having an inner reflective surface with predetermined optics and an outer surface. The inner and outer surfaces extend between proximal and distal ends. A lens is attached to the distal end of the housing. The lens and the inner reflective surface bound an enclosed chamber of the assembly. The assembly further includes a heat sink subassembly. The subassembly includes a heat sink and an electronic module. The electronic module has PCB electronics and at least one LED coupled in electrical communication with one another. The subassembly is mounted to the proximal end of the housing externally from the enclosed chamber.
