Abstract: A type 2 rectangular sealed beam headlamp unit wherein the ferrule bosses are positioned off the geometric center of the reflector to obtain equal ferrule boss heights by compensating for the inclination of the optical axis relative to the mechanical axis thereby greatly reducing reflector distortion caused by heat sinks in the molding of the reflector which result from varying glass thickness. The ferrule bosses are rotated with respect to the geometric axis such that the ferrule boss openings and surrounding distorted surfaces are removed from selected portions of the reflector surface to provide better selection of hot spot fluting.
