Auto leveling headlight system

Types of Auto-Leveling Headlight System

Auto-leveling headlights are designed to tilt up and down according to the load of the vehicle. The lights do not blind other road users. The auto-leveling headlight system has different types.

• Static headlight illumination control (SHS)

  SHS enhances visibility when turning corners. The system knows when the driver is turning and shifts the headlights to light the new path. With SHS, drivers won't have to turn their heads to see the road. The headlights auto-adjust to give a clear view of what's ahead.

• Dynamic bending light (DBL)

  DBL is an advanced headlight system in auto-leveling cars. It uses sensors to track the vehicle's speed and steering angle. When turning at higher speeds, the headlights move to light the curve. This way, drivers can see obstacles clearly and navigate turns safely. DBL provides extra safety during swift maneuvers by ensuring good visibility.

• Cornering lights

  Some cars come with cornering lights. These are extra bulbs that turn on when going around bends. They shine into the turn to give a better view of the side of the road. Cornering lights help spot pedestrians or hazards lurking off the main track. They maximize safety by improving side visibility in curves.

• Adaptive front lighting system (AFS)

  AFS is found on higher-end vehicles. This system automatically adjusts the headlight beam's direction and intensity based on factors like speed, steering input, and ambient light. AFS provides optimal lighting in various driving conditions, enhancing safety and comfort. With AFS, drivers can rely on intelligent headlights that adapt to the environment.

• Dynamic LED headlights

  Some modern cars use dynamic LED headlights. These high-tech lights can change their shape and brightness to avoid blinding other drivers while illuminating the road. Dynamic LED headlights offer precise and adjustable lighting. They improve nighttime driving safety for all road users through advanced control.
