Abstract
A vehicle glazing () wherein a light guide stack () is located between a portion of the inner transparency () and the outer transparency (). The light guide stack includes a polycarbonate film () that is bonded to the transparencies by layers of PET () that are secured to the polycarbonate film on one side by silicone () and that are secured to the transparencies on the other side by PVB (). The terminal end of an extending tab of the polycarbonate film forms an edge that is connected to a light bar () that such visible light propagates through the light bar and into the polycarbonate film through the edge. Visible light propagates through etchings in the smooth surface of the polycarbonate film to form an image. An extension of one of the transparencies protects the polycarbonate tab and supports the light bar during installation of the glazing into the vehicle portal.
