What is the purpose of adaptive front lighting system?
Adaptive front lighting systems (AFS) are an advanced automotive technology designed to improve visibility and safety for drivers. These systems automatically adjust the headlight beams to adapt to changing driving conditions, providing better illumination and reducing glare for other road users.
How Adaptive Front Lighting Systems Work
Adaptive front lighting systems use a combination of sensors, cameras, and electronic controls to monitor the vehicle's speed, steering angle, and surrounding environment. Based on this information, the system can dynamically adjust the headlight beam pattern, intensity, and direction to optimize lighting for the current driving situation.
- Beam Pattern Adjustment: The system can change the shape and spread of the headlight beams to provide better illumination around corners, on winding roads, or when the vehicle is turning.
- Beam Intensity Control: AFS can adjust the brightness of the headlights based on ambient light conditions, reducing glare for oncoming drivers in dark environments.
- Beam Direction Control: The system can swivel the headlights to follow the vehicle's steering, providing better visibility in the direction the driver is turning.
By adapting the headlight performance to the driving conditions, adaptive front lighting systems help drivers see more clearly, react faster, and avoid potential hazards on the road.
Benefits of Adaptive Front Lighting Systems
The primary benefits of adaptive front lighting systems include:
- Improved Visibility: The dynamic adjustment of headlight beams provides better illumination of the road ahead, enhancing the driver's ability to see obstacles, pedestrians, and other vehicles.
- Reduced Glare: By automatically adjusting the headlight intensity, AFS helps minimize glare for oncoming drivers, improving safety for all road users.
- Enhanced Safety: The improved visibility and reduced glare from adaptive front lighting systems can help drivers react more quickly to changing road conditions, potentially preventing accidents.
- Increased Driving Comfort: The automatic adjustment of headlight performance can reduce eye strain and fatigue for the driver, making long-distance driving more comfortable.
Adaptive front lighting systems are becoming increasingly common in modern vehicles, as automakers continue to prioritize safety and driver assistance technologies.
What does an adaptive front lighting system do?
Adaptive headlights improve driver visibility by dynamically adjusting their direction and brightness to match road conditions, such as by pivoting into a turn or automatically switching between high and low beams. This helps illuminate the path ahead more effectively, reduce glare for other drivers, and increase reaction time for enhanced safety.

How they work
- Pivot in turns: Sensors monitor steering wheel angle, vehicle speed, and road curvature to turn the headlights left or right, lighting up the path the car is taking into a curve.
- Automatic high beam assist: The system uses sensors to detect oncoming vehicles and automatically switches from high beams to low beams to avoid dazzling other drivers.
- Adaptive driving beam: More advanced systems use a "matrix" of LEDs to create a high beam that can block out specific areas where other vehicles are detected, allowing the rest of the road to remain illuminated.
- Cornering lights: At low speeds, some systems activate additional lights to provide a wider field of vision for sharper turns, such as when parking.
Benefits
- Improved visibility: They better illuminate curves and blind spots, making it easier to see pedestrians, animals, or road hazards.
- Increased safety: By extending the view ahead and helping drivers react faster, adaptive headlights can help reduce the risk of accidents, especially at night.
- Reduced glare: The systems automatically adjust to prevent blinding oncoming drivers, leading to a safer experience for everyone on the road.
How does AfS work at night?
How AFS works. AFS automatically turns on low beams according to vehicle speed and steer to provide better visibility.
Can I drive with an afs light on?
If the AFS indicator comes on and starts blinking while driving, pull to the side of the road when it is safe, and turn off the engine. If the AFS indicator keeps blinking, or starts blinking again while driving after turning the ignition switch to the ON (II) position, the AFS is not working properly (see page ).
What is Mazda's adaptive front lighting system?
Mazda's AFS automatically adjusts the angle of the vehicle's headlights, illuminating the direction of travel. Using sensors to measure vehicle speed and steering angle, AFS turns the headlights accordingly to help drivers see around a curve at night.
