Global headlamp
Systems and methods for a global headlamp. An example method includes obtaining configuration information indicative of a jurisdiction associated with a vehicle. Headlamp state information is accessed which includes multiple headlamp states. A current headlamp state of the multiple headlamp states is determined based on the configuration information. A propagation is output via a pixelated light source in a headlamp of the vehicle, the propagation representing a particular beam pattern which is compliant with the jurisdiction.

15. The vehicular system of claim 14 , wherein a first output propagation associated with a low-beam state for the selected current jurisdiction causes activation of first emissive elements included in a first threshold number of rows, and wherein a second output propagation associated with a high-beam state for the selected current jurisdiction causes activation of second emissive elements included a second threshold number of rows, and wherein the second threshold is greater than the first threshold.
