Abstract
A vehicle includes a window having a lighting system therein. The lighting system includes a layer of an optical medium, a light source and a lens array. The layer of the optical medium has a first interface and a second interface. The light source emits a light ray that is incident at the first interface and travels through the optical medium to exit the optical medium at the second interface. The lens array is configured to reduce an occurrence of total internal reflection of the light ray at the second interface.
