A luminous vehicle glazing (100, 200, 300, 400, 500, 600, 700, 800) comprising: - a first sheet of mineral or organic glass having a first main face and a second main face and an edge, - a peripheral light source (2, 2', 20) with an emitting face (21, 21') selected from an optical fiber and light emitting diodes (2, 2') each comprising a semiconductor chip on one support section of the diodes, the emitting face facing a side of the second face called injection side for a propagation of the injected visible and/or ultraviolet called UV light in the thickness of the first sheet, the first sheet then playing the role of a guide of the injected light, (the injection side optionally being partly recessed or even having a setback), - to form at least one luminous zone: - means for extracting the guided light via the first and/or the second main face, which are surface diffusion means of the first and/or the second main face or volume diffusion means in the first sheet, - and/or when the injected light is UV, means for converting the UV light to visible light via the first and/or the second main face, which are luminophores particularly on the first and/or the second main face - an optional added peripheral functional element, bonded to the first sheet, which is fluid-tight, in particular a functional element which is selected from an overmolding or a preassembled element, - a fluid-tight cap for covering the source (2, 2', 20), impermeable in particular to liquid water or even water vapor, - the cap, called a facial cap, that is to say, essentially facing the second face, joined by fastening means (81, 82, 83, 86) - to the first sheet, in particular of organic glass - and/or to a connecting part bonded to the first sheet, - and optionally to the functional element the cap having a general what is called inner face oriented toward the second face, the cap being associated with an interfacial element (5, 51, 5'), for the fluid-tight interfacial sealing, impermeable in particular to liquid water or even water vapor, which is arranged between the cap and the connecting part and optionally between the cap and the functional element or integrated with the cap, or integrated with the connecting part or integrated with the first sheet. -
