A displacement system for simultaneous displacement of a first and a second light module of a lighting apparatus, wherein the first light module is mounted so that it can swivel about a first swivel axis and the second light module is mounted so that it can swivel about a second swivel axis, and wherein the two swivel axes extend parallel to each other. The displacement system includes a first and a second control shaft, wherein the control shafts are mounted so that they can be rotated about their respective longitudinal axis and moved linearly in the direction of their longitudinal axis, wherein the first and the second control shaft are connected in a torque-proof manner to a first and a second rotary element, so that when the first rotary element rotates, the first control shaft is rotated in the direction of rotation of the first rotary element, and when the second rotary element rotates, the second control shaft is rotated in the direction of rotation of the second rotary element, and wherein a third rotary element is provided, which cooperates with the first rotary element such that when the third rotary element rotates, the first rotary element is rotated, and wherein the first rotary element and the second rotary element cooperate such that when the first rotary element rotates, the second rotary element is rotated in the opposite direction to the direction of rotation of the first rotary element, and wherein the first and the second control shafts are mounted in such manner that as a consequence of the rotations by the first and second rotary elements caused by the rotation of the third rotary element they move linearly in opposite directions along their respective longitudinal axes, and wherein the swivel axes extend that the two light modules are swiveled simultaneously and in the same direction about their respective swivel axis.
