That's to make sure you are not dazzling the traffic on the opposite site when you are at a stand still.
I need to recode my LMA to change this as my RHD (UK) car is now registered in Germany and has LHD housings fitted. hoping I can sort this myself as my first coding job.

The law of physics states that light travels in a straight line, and whilst BMW is unable to change this immutable fact of nature, it's true to say that the BMW driver can now see more than many other motorists. This is due to the introduction of an intelligent system in light technology - a revolutionary innovation the world over which allows the driver to literally light up the bends ahead.

Featuring variable headlight control, Adaptive Light technology anticipates in advance which direction the driver is taking and swivels the moving vario-xenon-module headlights in the appropriate direction. Unlike conventional headlights which only follow the steering wheel or the position of the front wheels, intelligent light control illuminates the road ahead even before you enter a curve or take a bend.

This is made possible by a system of sensors and computers which use the car's steering angle, road speed and lateral acceleration to recognise changes in course even before they happen. Adaptive Light Control even employs data from the in-vehicle satellite navigation system to ensure optimum illumination of the road ahead in every situation.


I have a 2004 745i with adaptive headlights. I was told by the dealer that for 2004 the adaptive headlights only move up and down to account for road conditions and vehicle loading. I'm skeptical. I thought for my car they should move sideways in a turn as described in the previous posting. Does anyone know how they are designed to work on the 2004 745i?

And I thought my '08 LCI has a malfunction when testing in standstill position, it did not work moving to the left side, only to the right. Thanks for the info explaining the proper function when car is not moving.

If you have xenon, then there must be a self-levelling system installed (at least in European countries) to avoid blinding others. This is the "move up and down" motion the dealer told you. This is standard on all xenon lights.

Now, the adaptive headlights feature is the option of implementing the left/right movement of the lights depending speed and steering wheel angle. You can easy check it by moving your steering wheel while parked against a wall; the lights will slightly move left-right. This movement is larger while driving.
