The present invention relates to a lighting vehicle glazing (3), comprising (i) an external glass pane (10) having an outer surface (P1) and an inner surface (P2) and an edge and (ii) an internal glass pane (11) having an outer surface (P3) and an inner surface (P4) and an edge (110), (iii) the first and the second glass panes (10, 11) being laminated together via at least a first plastic interlayer (14) having a thickness T1, (iv) a light-conducting plastic interlayer (12) having a thickness T2 lower than T1 in contact with the outer surface (P3) of the internal glass pane (11), the said light-conducting plastic interlayer being configured to conduct light coupled in at one of its end sides, which is materially bonded to the internal glass pane (11), (v) at least one light source (16) which is arranged such that light is coupled in at least one end side (122) of the light-conducting layer and/or at an end side (110) of the internal glass pane (11). According to the present invention, the light-conductive plastic interlayer (12) comprises a thermoplastic interlayer (120) provided with a functional layer (121) comprising light scattering particles applied to at least the surface the thermoplastic interlayer (120) in contact with the outer surface (P3) of the internal glass pane (11) and the light-conductive plastic interlayer (12) has decoupling means (13), via which a light exit of conducted light from the light-source (16) is caused on at least one of the light-conducting layer's main surface.
