Right lighting for more comfort and greater safety on the road ahead of you


Standard headlights shine straight ahead, no matter how the car is moving. More recently, headlights can react to steering, speed, and the slope of the road, to automatically adjust the lighting for the way ahead. This ensures drivers – and other road users – see more of the road, which can reduce injuries and deaths.

Static automatic-levelling, or self-levelling, headlights have a sensor that measures the tilt of the car relative to the road – such as when the car is heavily loaded. LED and XENON lights always have static automatic levelling, halogen lamps have manual levelling.

Cornering and dynamic bending lights adapt the direction of the light to the road ahead: When the car turns right, the lights illuminate to the right. When the car turns left, the lights illuminate to the left. This offers up to 90% more visibility in curves and intersections.

There are two commonly used systems:

Cornering systems that turn on a fixed, extra lamp when you use your turn signals.
Dynamic bending systems use information from the speed of the car and the angle of the steering wheel to control servomotors that turn the whole lamp unit.

Technical advances have been made in recent years to develop Advanced Front Lighting Systems. These are normally xenon or LED lamps that are automatically controlled to provide the right amount of light where it is needed on the road ahead.

In 2008, a study conducted by the Insurance Institute for Highway Safety estimated that adaptive front lights could help avoiding about 4% of front to rear, single driver and run-off road accidents. In the US these types of crashes account for 143,000 accidents a year, involving 2,553 fatalities and 31,000 injuries. In Europe the University of Darmstadt is conducting similar research for LightSightSafety.

High beam low beam
As well as auto-levelling and cornering, fully adaptive front light systems automatically adapt the light beam pattern to the driving environment.
  • Country light is the traditional lighting. Adaptive systems sense the traffic ahead to automatically switch between low and high beams.
  • Motorway light increases the visibility range for high-speed travel on motorways.
  • City light increase peripheral visibility to make it easier to see pedestrians and cyclists, and to reduce glare for oncoming traffic.
  • Adverse weather light increases visibility and reduce glare in rain, snow and fog.
Advanced Front Lighting System
A further development is glare free high beam (adaptive driving beam). This uses a camera built behind the windscreen to gather information on the traffic ahead (oncoming or travelling in the same direction), and to use this to progressively adjust the headlamp. In effect this gives you a continuous transition between high and low beam to provide optimal visibility, while avoiding dazzling other drivers.
