No, they do not "self level", they are simply swinging up to fill in the high beams, and also tilt up and down at start up. “Self leveling” is only available on factory installed lits, and continuously adjusts the headlight beam angle to match the car's tilt and pitch angles (required is certain European countries). “Self leveling” feature is nearly impossible to install post delivery due to the complexity of the wiring and sensor set up. A quick way to discern factory lits from post delivery installs is to connect the car to either a PST II or PIWIS unit, which can run diagnostics on the factory systems, but not the post delivery installs..............
