Abstract
A lamp assembly configured to be mounted to a vehicle includes a housing configured to be coupled to a vehicle and at least one light source disposed at least partially within an interior of the housing. The lamp assembly further includes a transparent polymeric lens coupled to the housing so as to substantially enclose the interior of the housing and the at least one light source. The transparent polymeric lens has a chromium-based reflective coating coated on at least a first area of an outer surface thereof. With the at least one light source electrically-connected to the vehicle, the chromium-based reflective coating is at least partially permeable to at least some light which is emitted by the at least one light source and passed through the transparent polymeric lens. At least a second area of the outer surface of the transparent polymeric lens is devoid of the chromium-based reflective coating.
