For the record: the difference between Adaptive Headlights and Cornering Lights:
"Adaptive Headlights
The Adaptive Headlights cast their beam in the direction of the curve and ensure better visibility and more safety during night drives on winding roads.
Sensors measure speed, steering angle and yaw (degree of rotation around the vertical axis). Based on this information, small electric motors turn the headlights left or right so the beam falls on the road ahead, guiding you into the bend.
Headlight beam throw control (a model-specific function) means the front headlights are raised at high speeds and lowered at slower speeds, which results in a wider beam for inner-city driving.
The adaptive headlight range control (a model-specific function) takes into consideration the vertical curve of the road. The headlight beam throw control is lowered when driving over a knoll and raised when the vehicle is in a dip.
The result: every single curve is illuminated and the oncoming traffic isn’t dazzled unnecessarily. Driving at night is even safer, particularly when visibility is poor.
Adaptive Headlights are only active when the vehicle is pulling away. They stay switched off when the BMW is in reverse and when the steering wheel is turned to the left while the vehicle is stationary (e.g. when pulling out of a parallel parking space to avoid dazzling oncoming traffic).
Adaptive Headlights are complemented by cornering lights. These are automatically activated at speeds of up to 70 km/h and improve visibility in the immediate vicinity of the vehicle, which is useful when driving along hairpin bends, turning or parking."

"Cornering lights
Cornering lights provide additional illumination of the area to the side of the vehicle, making night-time parking and turning safer.
Cornering lights compliment the functionality of Adaptive Headlights. While Adaptive Headlights provide superior illumination of curves when driving at normal speeds, cornering lights give you better lighting when carrying out low-speed manoeuvres: parking, turning into a driveway, u-turns and taking extremely winding roads, for example.
To provide this additional light, the fog lamps are fitted with integrated swivelling reflectors; alternatively, the headlights are equipped with an additional lamp. When the indicator is activated at speeds below 40 km/h, these lights illuminate an area to the side of the vehicle, up to 80° of the direction of travel.
After the corner is taken, the cornering lights dim and extinguish automatically. Cornering lights also facilitate safe reversing: when reverse gear is selected, both the left and right lights illuminate the area around the vehicle."
