| 1. A system for dynamically recalibrating an adaptive lighting system, the system comprising:
a lamp pivotably mounted to a frame, wherein the lamp is configured to rotate about a central axis between a first hard stop
and a second hard stop, a center line being located between a first hard stop and a second hard stop, a center line being
located between the first and second hard stop;
a stepper motor coupled to the lamp, the motor configured to rotate the lamp between the first hard stop and the second hard
stop; and
a control module in electrical communication with the motor, wherein the control module is configured to instruct the motor
to rotate the lamp between a first soft stop and a second soft stop, the first soft stop being located between the first hard
stop and the center line and the second soft stop being located between the second hard stop and the center line; and
wherein the control module is further configured to instruct the motor to rotate the lamp to the first hard stop when the
lamp positioned at the first soft stop and to recalibrate the control module using the first hard stop as a reference point;
wherein the lamp is a headlamp for an automobile.
