My Morrettes came with leveling motors. I removed them before I installed the lights. It makes access to the headlamp adjusting screws much easier. Keep in mind that the leveling motors are designed to only lower the headlights. When used properly, the headlights are aimed properly with the leveling motors in the full up position and then lowered when you have a load in the back of the vehicle. On cars equipped with factory HID lamps, this is done automatically using a ride height sensor of some sort. Usually it is linked to the rear suspension. I've seen some manually controlled units on old Euro-spec Mercedes. Of course, this is before the advent of HID lamps. All this is to prevent you from blinding oncoming traffic.
