A lighting device for vehicles comprising an housing body having a front inlet opening arranged to face in use toward a forward driving direction of the vehicle, a main lighting module and at least two secondary lighting modules arranged inside the housing body, facing the inlet opening, the at least two secondary lighting modules being carried rotatable in relation to the housing body and to the main lighting module, each around a respective its own first axis (A,B,C), the first axes (A,B,C) being arranged parallel to each other and transverse to an horizontal plane in use, and around at least a second axis arranged perpendicular to the first axes; said main lighting module being designed to generate selectively or simultaneously, when it is switched on, a first light beam configured for a dipped beam function and a second light beam configured for a high beam function, said first and second light beam forming on a test screen placed in front of the lighting device a first light projection and a second light projection, respectively; and said secondary lighting modules being designed to generate each, when they are switched on, a third light beam forming on the test screen a third light projections (T1,T2,T3) which may partially overlap the first and/or the second light projections (LP1,LP2); the lighting device further comprising a control unit to switch on/off selectively the main lighting module and the secondary lighting modules and to rotate each secondary lighting module around either the first (A,B,C) or the second axes; characterized in that, in combination: i)- the control unit is configured to make all the third light projections (T1-T3), when it switches on all the secondary lighting modules, to overlap for the major part thereof on the test screen onto one another and onto the second light projection, substantially at the center of the second light projection, when said main lighting module is also switched on to generate said second light projection; and ii)- the control unit is configured to carry out a simultaneous rotation of an at least one or of all the secondary lighting modules around the first and second axis thereof by making the third light projection (T1-T3) of the at least one or of all the secondary lighting modules to describe on the test screen a trajectory passing through an optical axis of the main lighting module, the trajectory being a linear trajectory or being a trajectory mathematically represented by a polynomial function of the 3 rd degree. i)- the control unit is configured to make all the third light projections (T1-T3), when it switches on all the secondary lighting modules, to overlap for the major part thereof on the test screen onto one another and onto the second light projection, substantially at the center of the second light projection, when said main lighting module is also switched on to generate said second light projection; and ii)- the control unit is configured to carry out a simultaneous rotation of an at least one or of all the secondary lighting modules around the first and second axis thereof by making the third light projection (T1-T3) of the at least one or of all the secondary lighting modules to describe on the test screen a trajectory passing through an optical axis of the main lighting module, the trajectory being a linear trajectory or being a trajectory mathematically represented by a polynomial function of the 3 rd degree.
