Abstract

A headlamp assembly for a motor vehicle including a lens and a housing that cooperate to define an inner chamber that is generally isolated from the atmosphere. A heat sink includes a fin portion that extends from the inner chamber so as to be exposed to ambient air. A light source is located within the inner chamber and is supported on a base portion of the heat sink. The heat sink conducts heat from the light source to air located exterior of the chamber.
