An automotive lighting unit wherein the lighting assembly that backlights the front half-shell comprises: at least one light-guide body made of photoconductive material, which is placed inside the rear body and is structured to channel, by total internal reflection and towards said transparent or semi-transparent portion of the front half-shell, the light that enters into the light-guide body through a light-incoupling end or sidewall of the same light-guide body; an active light deflector device which is placed inside the rear body, facing the light-incoupling end or sidewall of said light-guide body; and an electrically-powered light source which is placed inside the rear body and emits, on command, a collimated light beam towards the active light deflector device; the active light deflector device being adapted to reflect/divert said collimated light beam towards the light-incoupling end or sidewall of said light-guide body, so that the collimated light beam can enter into the light-guide body and then travel inside the light-guide body by total internal reflection.
