Abstract
Vehicle light comprising a container body that houses at least one light source, a lenticular body, a light guide, the light source, so as to receive the light beam and transmit it to a light outlet wall. The light guide comprises a body that defines the propagation direction of the light beam inside the body by total internal reflection. The body has a first groove, comprising a plurality of first holes, defining cylindrical or spherical optics that produce a scattering of said 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 are blind with respect to a thickness of the body of the light guide, penetrating from a first face of the body for a first depth less than said thickness.
