A system may have windows. A window in the system may have first and second window layers such as structural layers of glass. The window may have a light guide layer between the first and second window layers. The light guide layer may have cladding layers and a core layer between the cladding layers. The core and cladding refractive index values may be selected so that the refractive index of the core is greater than the refractive index of the structural layers of glass while the refractive index of the claddings is less than the refractive index of the structural layer of glass. Light-scattering structures may be formed on the light guide to extract some of the light within the light guide and thereby provide illumination for the system.
