Claim 19:
20. A vehicle surface, comprising:
a first transparent layer;
a second transparent layer;
an edge-lit light guide plate positioned between the first transparent layer and the second transparent layer;
a first refractive layer positioned between the first transparent layer and the edge-lit light guide plate, the first refractive layer including a first absorbing portion and a first transparent portion; and
a second refractive layer positioned between the second transparent layer and the edge-lit light guide plate, the second refractive layer including a second absorbing portion and a second transparent portion,
wherein the first absorbing portion and the second absorbing portion are adapted to absorb light rays emitted from a light source of the edge-lit light guide plate that reach the first refractive layer or the second refractive layer at greater than a critical angle at which light rays escape from the edge-lit light guide plate.
