In conjunction with bi-xenon headlights featured as an option, 5 Series Sedan fitted with the latest generation of Adaptive Headlights including Bending Lights for variable light distribution and adaptive headlight range control. Adaptive Headlights illuminate the road ahead clearly and brightly under all conditions, following curves and winding routes. In the process the headlights turn in the same direction as the steering wheel, following the steering, the yaw rate and the speed of the car. The Bending Light function is integrated in the headlights, switching on an additional light beam every time the car takes a bend in order to illuminate the road ahead in the direction the driver is following.
Adaptive headlight range control also takes the vertical contours of the road into account, with the light beam being lowered or, respectively, raised when driving over crests, through a tunnel or on a steep ramp in order to illuminate the road ahead exactly the right way, without dazzling oncoming traffic. A further feature of the Adaptive Headlights is variable light distribution optimising the illumination of the road in accordance with current requirements also on a straight route. In this case the innovative control function operating in accordance with road speed automatically enlarges the driver’s field of vision by enlarging the light beam appropriately.

The optional High-Beam Assistant in the new BMW 5 Series offers additional safety when driving at night. Taking current driving conditions into account, this system switches the high beam on and off automatically as required, consistently giving the driver optimum visibility and at the same time relieving him of the chore to constantly monitor the high beam in the case of oncoming traffic. Processing images generated by a camera integrated in the interior mirror, the High-Beam Assistant recognises vehicles driving ahead in the same direction up to a distance of approximately 400 metres or 440 yards and oncoming vehicles up to a distance of about 1,000 metres or 1,100 yards. A further feature is that the high-beam is switched off automatically as soon as the surrounding light reaches a certain level of intensity and is therefore bright enough.
