Automotive lighting unit

An automotive lighting unit comprising:

• a rear casing adapted to be fixed to the vehicle;
• a front half-shell with a substantially transparent structure, which is arranged to close the mouth of said rear casing;
• and at least one lighting assembly, which is located inside the rear casing and is adapted to backlight a corresponding transparent or semi-transparent sector of the front half-shell comprises:
• a light source, which is placed inside the casing and is adapted to emit and direct a light beam towards the front half-shell;
• and,
• a Kohler optics, which is interposed between the light source and the front half-shell, so as to be crossed by the light beam arriving from the light source, and is structured so as to give, to the light beam reaching the front half-shell, a pre-established shape determined by the shape of the lenses that contribute to form said Kohler optics.
