A headlamp assembly including a light source element, an outer lens, a fan, and a bezel structure, wherein the bezel structure is disposed forward of the fan in a vehicle-longitudinal direction and includes an air flow directing feature directing air flow from the fan toward the inner surface of the lens. Embodiments of the headlamp assembly generate light using low-temperate light emitting diodes (LEDs) and direct air flow over components thermodynamically coupled to the LEDs such that the air absorbs heat from the components and distributes the heat throughout the headlamp assembly, especially on the inner surface of the outer lens to reduce the condensation thereon. Further, embodiments may include a bezel structure having a pair of vehicle-forward concave sections disposed at the forward end of the bezel structure that disperse air through the headlamp assembly in a wide aperture to distribute thermal energy more equally throughout the headlamp assembly.
