A Mercedes-Benz featuring bi-xenon headlamps
with the sophisticated Active Light System, which follow the
movements of the steering wheel to enhance a driver's range of
vision when cornering at night, has recently been released.
The active cornering headlamp system is set to enhance
night-driving safety and is now available as an option on the
popular E-Class sedan and the all-new E-Class estate.
The Active Light System, which is based on the bi-xenon
headlamps used in the Mercedes-Benz E-Class, enables the headlamps
to follow the direction in which the driver is steering,
swiveling promptly in the appropriate direction as soon as the
driver enters a bend and improving road illumination by up to 90
percent as a result. The illumination range of the dipped beam
headlamp on entering a 190-metre radius bend, normally around 30
meters, is extended by 25 meters if this new headlamp technology
is fitted. This matching of light distribution to steering angle
means that the driver gets an early view into the bend and can
adapt his or her driving accordingly.
The Active Light System operates in both low and main-beam mode
and continuously adapts to the speed of the vehicle at all times.
In other words, the headlamps follow steering wheel movements
almost instantly when the vehicle is traveling at high speed, but
less swiftly when the car is proceeding at a slower rate, thus
ensuring that the light is distributed precisely as the driver
The Active Light System is controlled by a microprocessor
integrated in the car's electronic data network, which means that
it is continuously supplied with real-time information from the
steering angle and road speed sensors.
Dynamic headlamp range adjustment - a standard feature of
Mercedes-Benz models equipped with bi-xenon headlamps - also works
with the new cornering headlamp system in order to prevent
oncoming drivers from being dazzled. Controlled by sensors, this
system detects all the movements of the vehicle body and adjusts
the headlamp settings accordingly.
