The term “adaptive front-lighting system” (AFS) refers to headlights that turn in the direction a car is turning, illuminating more of the road in that direction rather than straight ahead.
Many automakers, including Honda, Mazda, Toyota, and others, refer to adaptive front illumination. They are also known as adaptive headlights or curve-adaptive lights, and other manufacturers have their own brand names for them, like the Genesis Adaptive Cornering System and the Porsche Dynamic Light System.

What does my Lexus’ AFS off signify?
14:15 on August 28, 2018. In order to prevent the headlights from pointing too high if there is weight in the back, AFS adjusts the headlamp level to how the vehicle is sitting. You cannot disable the adaptive system because it must be present by law in any car equipped with LED or HID lighting.
What does the AFS off light imply when it illuminates?
When it is safe to do so, pull over to the side of the road and turn off the engine if the AFS indication illuminates and begins blinking while you are driving. When driving with the ignition switch in the ON (II) position, if the AFS indicator blinks continuously or blinks once more, the AFS is malfunctioning (see page ).
What does AFS on an automobile mean?
A well-illuminated field of view is one of the most crucial elements in reducing driver tiredness and enhancing safety during nighttime driving. According to the conditions of the road, the Adaptive Front-lighting System (AFS) improves the distribution of headlight light. The device directs the low-beam headlights in the direction the driver desires to go based on vehicle speed and steering input.
The technology improves the driver’s field of vision and visibility around curves and at intersections during nighttime driving by illuminating a greater distance and brighter than halogen headlights do. When combined with auto-leveling, the technology provides a consistent light distribution that is unaffected by the location of the vehicle. When a car’s back is loaded down with a lot of people or luggage, its position varies when driving over a bump or up a slope, and the system maintains the lighting axis, it helps keep drivers of incoming vehicles from being blinded.
How is AFS light operated?
Modern vehicles dynamically change the headlights to try to improve nighttime vision. In this post, we’ll first look at this technology’s benefits. The fundamental building blocks and design issues will then be briefly covered.
Introduction
The goal of adaptive front lighting systems (AFS) is to dynamically change the vehicle’s headlights to provide the driver with the best possible nighttime visibility without endangering the safety of other road users. When the car steers or the road is uneven, the AFS uses stepper motors to regulate the headlight angle. Additionally, the adaptive mechanism seeks to prevent a direct glare from hitting approaching cars. It makes use of headlamps with an array of LEDs.
Some of these LEDs automatically dim depending on where the approaching car will be. In this manner, the driver’s side is dimmed while the area around the approaching car is lit. The position of the approaching vehicle is discovered by the AFS using image sensors. Figure 1 demonstrates how the AFS modifies the headlights to lighten the approaching car’s driver side.
How can I determine if I have AFS?
When you start the car with the lights on, if your lights move left and right before immediately returning to the center, you have AFS. According to my recall, the AFS won’t work when the car is at a stop; following initial calibration, the lamps must move when the car is going.
How do you use nighttime daytime running lights?
Some models come with an extra set of daytime running lights. In essence, this technology dims the headlights from their normal setting throughout the day to improve visibility for other drivers. It is especially useful for drivers at sunrise and dusk, when glare can make it difficult for them to see other cars. Your daytime running lights must be turned on in order to:
- Put the key in the “on” position.
- Put the headlights in parking light mode, auto light mode, or off.
- If these requirements are satisfied, the system ought to activate automatically.
- If the transmission is in park, your daytime running lights won’t switch on.
- If the parking brake is applied, a manual gearbox car’s lights won’t turn on.
How do the headlights on a Lexus RX 350 switch off?
Turn on the high lights by pulling the lever in your direction. To turn them off, pull back on the lever. With or without the headlights on, the high beams might flash. lighting switch
- Cut the daytime off. operating a light system
- the side markers, the headlights, the parking,
- the tail, parking, side marker, and license plate.
THE TECHNOLOGY BEHIND IT
Adaptive headlights are not permanently locked in place like regular headlights, which are only able to illuminate the area directly in front of you. These headlights use electronic sensors that use your steering angle to determine which way to swivel in accordance with the direction of your car.
WHAT YOU NEED TO DO
Use these headlights as you normally would, and be aware of any objects or other cars they may be shining on, especially when driving around curves. Always look ahead when driving to check for potential risks or impediments.
TIPS FOR USING IT
- Avoid oversteering at all costs or you risk losing control if you don’t respond quickly enough to a hazard.
- As you approach a curve, slow down and exercise caution.
- It’s a good habit to look toward the white lines on the side of the road in front of you when approaching oncoming automobiles with your high lights on to assist protect you from being blinded.
What is control of adaptive lighting?
To increase the safety of nighttime transportation, a new lighting concept called Adaptive Light Control (ALC) is being developed. By continuously adapting the headlamps to the current driving situation and environment, ALC enhances the headlamp lighting. The transition from offline to online (real-time) simulation of light distributions in the driving simulator has been completed successfully in order to ensure rapid prototyping and early testing. The interactive creation of novel light distributions in various driving scenarios and environments was made possible by this real-time simulation. To enable additional testing under real-world driving situations, the solutions are immediately ported to actual vehicles.
Results of the development of moveable headlights are reported in this study. Path prediction based on vehicle dynamics and navigation system route vectors is used to regulate these headlights. An introduction of the fundamental idea behind the Adaptive Light Control system is provided, along with an illustration of the differences between static and dynamic light distributions.
