Abstract: A lighting device for a vehicle headlight, the lighting device having a first light module (105), a second light module (106) and a third light module (107), wherein, when the modules are installed in a vehicle, the first light module generates a first overall light distribution (A), the second light module generates a first partial light distribution (F), and the third light module generates a second partial light distribution (Z), these distributions being in a region in front of the vehicle. When the first and second light modules are illuminated at the same time, the first overall light distribution at least partially overlaps the first partial light distribution, forming a second overall light distribution (AF). The second partial light distribution lies underneath the hh line and at least partially overlaps the second overall light distribution (AF). When all three light modules are activated simultaneously, a third overall light distribution (AF?) is formed.
