Multifunction headlamp assembly for motor vehicle

The projector unit has two projector devices arranged on a front side of a vehicle. The devices produce light beams (401, 402) respectively. The beams are identical in the configuration of the unit. One device has a mechanism to modify the beam (401) and to obtain another configuration of the unit. The latter configuration produces a total light beam (400) by superposition of a modified luminous beam on the beam (402). An independent claim is also included for a vehicle equipped with a projector unit.
