Abstract
An illuminated vehicle signaling glazing unit, including: a first transparent sheet made of mineral glass including a first main face configured to be directed toward outside the vehicle, a second main face configured to be directed toward inside the vehicle, and an edge face; one or more light sources, or light-emitting diodes, each including a light-emission face opposite the edge face, light emitted by the light sources being guided into the first sheet between the first and the second main faces thereof; a mechanism extracting light in at least one region of the first or second main faces of the first sheet or within a thickness of the first sheet; and an opaque layer formed from ink or from enamel, situated toward the inside of the vehicle with respect to the extraction mechanism and totally masking the extraction mechanism of the light to render it invisible from inside the vehicle.
