A pedestrian protection headlamp assembly for a motor vehicle allows the headlamp to yield rearward in a controlled, energy-absorbing manner in order to cushion the impact experienced by a pedestrian struck by the vehicle. The rotation axial unit further includes an openingshutting axis for connecting the main unit and the flip unit in a mutually rotatable way and a rotation axis for connecting the flip unit in a way of rotating the flip unit across the above rotation in the horizontal direction, and when the flip unit is opened and rotated across, it is used as a video camera with a monitor. The screw head is embodied so as to be able to be inserted into an undercut longitudinal groove of the other workpiece.
