Abstract
A method of forming a headlamp assembly includes molding a one-piece lens from a substantially clear polymer material having a slightly yellow tint. A blue dye is infused into an outer surface of the lens to a maximum depth of about 6-10 microns such that the outer surface has a blue appearance. A core of the lens is substantially clear or slightly yellow. UV stabilizers may also be infused into an outer surface portion of the polymer material. The lens and an LED light source may be positioned inside a housing have a clear side wall. The blue dye alters the appearance of the lens without significantly reducing the light-transmitting properties of the lens.
