A vehicle lighting system comprising: at least a pair of two-dimensional image forming devices (10L, 10R) whose shining areas (AL, AR) are each divided into a plurality of elements and which are respectively configured to form an optical image of an arbitrary shape by changing the elements arbitrarily, wherein the pair of two-dimensional image forming devices (10L, 10R) are provided individually for mounting at a left-hand side and a right-hand side of a vehicle, wherein the shining area (AL; AR) of at least one of the two-dimensional image forming devices (10L; 10R) differs from the shining area (AL; AR) of the other of the two-dimensional image forming device (10L; 10R), wherein the shining area (AL; AR) of the one two-dimensional image forming device (10L; 10R) is positioned above the shining area (AL; AR) of the other two-dimensional image forming device, wherein the shining area (AL; AR) of the one two-dimensional image forming device (10L; 10R) is wider, in a vertical direction when the vehicle lighting system is mounted in the vehicle, than the shining area (AL; AR) of the other two-dimensional image forming device (10L; 10R), characterized in that the one two-dimensional image forming device (10L; 10R) has an optical axis which is set as to be positioned above a horizontal line, and the other two-dimensional image forming device (10L; 10R) has an optical axis which is set so as to be positioned below the horizontal line, and the optical image formed by the one two-dimensional image forming device (10L; 10R) is used for a first application different from a second application of the optical image formed by the other two-dimensional image forming device (10L; 10R) such that the optical images which are formed by the pair of two-dimensional image forming devices (10L; 10R) do not have to be superposed on each other, and the one two-dimensional image forming device (10L; 10R) is configured to form a pedestrian illuminating pattern for illuminating a pedestrian, an Adaptive Driving Beam, ADB, distribution pattern or an Over Head Sign, OHS, light distribution pattern for illuminating a sign placed above the road surface, which is the first application, and the other two-dimensional image forming device (10L; 10R) is configured to form a lane forming pattern for illuminating a driving lane on the road surface, a direction indicating light distribution pattern for indicating a traveling direction of a vehicle on the road surface, a map of a navigation system on the road surface, or an instrument panel such as a speedometer on the road surface, which is the second application. at least a pair of two-dimensional image forming devices (10L, 10R) whose shining areas (AL, AR) are each divided into a plurality of elements and which are respectively configured to form an optical image of an arbitrary shape by changing the elements arbitrarily, wherein the pair of two-dimensional image forming devices (10L, 10R) are provided individually for mounting at a left-hand side and a right-hand side of a vehicle, wherein the shining area (AL;
