A vehicle window assembly includes a vehicle structure, a window panel and a light source. The vehicle structure defines a viewing aperture. The window panel is mounted to the vehicle structure and covers the viewing aperture. The window panel has a peripheral edge surrounding a first window surface and a second window surface opposite the first window surface. The first window surface includes an etched section. The light source is mounted to the vehicle structure adjacent to a portion of the peripheral edge of the window panel such that light from the light source is directed to the portion of the peripheral edge of the window panel. The light travels in a lateral direction through the window panel selectively illuminating the etched section.
