Automotive lighting apparatus (1) comprising at least one lighting assembly (4) which emits light on command, and is located inside the rear body (2) in order to selectively backlight a corresponding transparent or semi-transparent front half-shell (3); the lighting assembly (4) comprising: a radially emitting optical fibre (6) of given length; an electrically-powered, collimated light source (5) which is located inside the rear body (2), in front of a proximal end (6a) of the optical fibre (6), and is adapted to selectively direct, towards the same proximal end (6a), a collimated light beam (r) that enters into and travels inside the optical fibre (6); and an electronic control unit (7) which commands said collimated light source (5) and is adapted to deactivate the collimated light source (5) to interrupt/ prevent the emission of said collimated light beam (r), when the ratio between the intensity of the light reflected/ dispersed outside of the optical fibre (6) at the proximal end (6a) of the fibre, and the intensity of the light exiting from the distal end (6b) of the fibre, deviates from a predetermined reference value.
