Abstract

Vehicle light comprising a container body, a lenticular body, a light guide, including a body having a prevailing longitudinal extension (L) that defines the propagation direction of the light beam inside the body by total internal reflection. The body has a first breakline that extends from the first to the second side wall. The first breakline includes a plurality of first holes that produce, through successive refractions, a scattering the light rays (Ri) towards the light outlet wall so as to emit a light beam with opalescent effect. The first holes are adjacent to each other without interruption, and the first holes of the first breakline are pass-through with respect to a thickness of the body of the light guide, penetrating from a first face to a second face of the body for a depth equal to the thickness.
