Interior and exterior iridescent vehicle appliques
A vehicle applique is provided that includes a substantially transparent substrate defining first and second surfaces, a decorative film positioned on the first surface of the substrate, and an over-mold positioned over the film. The over-mold defines at least one diffraction grating and a light source is positioned proximate the second surface of the substrate. The light source is configured to emit light through the substrate and the over-mold.
