Abstract
A lighting module for a vehicular bumper includes at least one light source and a transparent polymeric portion configured to be coupled to a vehicular bumper so as to form at least part of the vehicular bumper. The transparent polymeric portion has a chromium-based reflective coating coated on an outer surface thereof configured to be at least partially permeable to light emitted by the at least one light source. At least one etching in the chromium-based reflective coating is devoid of the chromium-based reflective coating. With the at least one light source electrically-connected to a vehicle, light emitted by the at least one light source is reflected and distributed by at least one light reflector, substantially within at least one light chamber and towards the transparent polymeric portion, so as to simultaneously pass through the chromium-based reflective coating and the at least one etching in the chromium-based reflective coating.
