1. A headlamp assembly having low beam and high beam operation modes comprising:

  • a light source;

    a reflector surface adapted to reflect light from the light source outward;

    a condenser lens positioned at a distance from the light source such that light from the light source hits the reflector surface and is reflected outward to the condenser lens, the condenser lens adapted to collimate the light passing therethrough; and

    an opaque shield positioned between the light source and the condenser lens, the opaque shield being moveable between a first position, where a portion of the light reflected from the reflector surface is blocked from reaching the condenser lens, and a second position, where substantially all of the light reflected by the reflector surface is allowed to reach the condenser lens;

    the condenser lens having a first segment and a second segment wherein when the opaque shield is in the first position, substantially all of the light from the light source is reflected only to the first segment of the condenser lens, and when the opaque shield is in the second position, light from the light source is reflected to the first and second segments of the condenser lens.
