Abstract
A lamp or lens assembly for a motor vehicle that includes electrically conductive traces for defogging or deicing the lens. Aspects include a light transmissive lens coupled to a lamp housing. The light transmissive lens may define a curved cross-section with a curvature extending across the length and/or the width of the lens. The lens may include one or more electrically conductive traces positioned on a surface of the lens, the electrically conductive traces optionally extending across and curving with the curvature of the light transmissive lens. One or more coatings may optionally cover the conductive traces and a portion of the lens surface leaving portions uncovered. The electrically conductive traces may extend outwardly away from the surface of the lens with height that is greater than their width.
