A headlamp assembly (10) for producing high and low beam patterns includes a housing (12) having a reflector (18). The reflector (18) includes high (22) and low (20) beam reflector surfaces. A light source (24) is disposed within the housing (12) for producing light rays projecting towards the high and low beam reflector surfaces. A plurality of shafts (26) extends alongside the light source. A drive (74) is operatively connected to the plurality of shafts for rotation thereof. A shield (64) is connected to the plurality of shafts (26). Activation of the drive (74) rotates the plurality of shafts (26) to selectively move the shield (64) between an open position, in which the light rays project towards and reflect off of the high beam reflector surfaces to produce the high beam pattern, and a closed position, in which the light rays project towards and reflect off of the low beam reflector surfaces to produce the low beam pattern while the shield blocks a portion of the light rays from projecting towards the high beam reflector surfaces.
