Abstract
A modular headlamp assembly includes a low beam headlamp module, a high beam headlamp module, and front turn/parking lamp module. The low beam headlamp module and the high beam headlamp module are supported by a reflector carrier. Each of the high and low beam headlamp modules includes a heat sink and mounting assembly with a heat sink portion bisecting a reflector member. The headlamp includes a lens with a wire heating element embedded therein and a wire heating element circuit board affixed to the lens. A thermistor is affixed to the lens for sensing when the lens reaches a predetermined condition and a micro-controller is provided for activating or deactivating the wire heating element based on the predetermined condition sensed by the thermistor.
