A system may have windows. Each window may have light guide structures. The light guide structures may be formed between inner and outer glass layers. Light sources may emit light into the light guide structures. The light guide structures may include light guide core layers that guide light from the light sources across the window. Light-scattering structures may be provided to extract light from the light guide core layers. Some of the guided light may be extracted inwardly to serve as interior illumination for the system. Some of the guided light may be extracted outwardly. The outwardly extracted light visually obscures the interior region from the outside of the system, thereby providing system occupants with privacy.
