Stepper Motors For the Adaptive Headlights
WARNING: This page does not describe the selected car, but rather 94 other vehicles, including the 2013 BMW X6, 2012 BMW X6, 2011 BMW X6, 2010 BMW Z4, and 2010 BMW X6 M. However, it is still accessible from the selected car via links, so may be relevant.
The stepper motors turn the positioner modules in the bi-xenon headlights.
The stepper motors move the headlights vertically and horizontally (vertically = up and down for automatic headlight range adjustment;
horizontally = left and right for the adaptive headlights function).
The positioner modules execute the movement.
