Vehicle light comprising a portion of light emission with opalescent effect

A vehicle light capable of emitting a light beam with opalescent effect, said vehicle light comprising:

• a container body that delimits a containment seat that houses at least one light source suitable to emit, when electrically powered, a plurality of light rays defining a light beam to propagate outside of the vehicle light,
• a lenticular body, that partially closes the containment seat and is suitable to be crossed by said light beam produced by the light source,
• a light guide facing, in correspondence of a light inlet wall, to said at least one light source, so as to receive the light beam from said light inlet wall and transmit the light beam to a light outlet wall, facing the lenticular body,
• wherein the light guide comprises a body having a prevailing longitudinal extension that defines a propagation direction of the light beam inside the body by total internal reflection, a first and a second side wall substantially parallel to said prevailing longitudinal extension,
• wherein the body has a first groove, which extends from the first to the second side wall, the first groove comprising a plurality of first cylindrical or spherical holes, defining cylindrical or spherical optics suitable to realize cylindrical or spherical caustics that produce, through successive refractions, a scattering said light rays towards the light outlet wall,
• wherein said first holes are adjacent to each other without interruption, and
• wherein said first holes of the first groove 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.
