This invention proposes lighting apparatus, for a vehicle having two passing lights for producing a passing beam, which are adapted to pivot to a position deflected to the left or to the right when the vehicle is on a left-hand bend or a right-hand bend, respectively, together with two auxiliary headlights for giving an auxiliary regulation light beam. The apparatus also includes a central unit which, when it detects failure of a passing light in its deflected position, causes the faulty passing light to be extinguished and at least one auxiliary headlight to be lit, so that the auxiliary headlight compensates for the extinction of the faulty passing light, by producing a compensating light beam which has regard to the maximum permitted regulation photometric values above a horizontal longitudinal plane.
