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 the Lexus AFS light mean?
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.
How should I interpret the AFS off light?
When the shift lever is in the R position, AFS is disabled. In conjunction with the automatic headlamp adjustment system, the AFS detects variations in vehicle height brought on by driving circumstances and the weight of passengers and cargo. The system then automatically adjusts the vertical aim of the low beam headlights to account for load.
My AFS light is flashing; why?
The adjustable front lighting system (AFS) aids in increasing visibility while driving at night.
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 ). Have your dealer check out the AFS.
What does AFS on a dashboard of a car 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.
What is adaptive lighting in cars?
Adaptive headlights typically have bulbs that rotate in the direction of the vehicle’s movement or speed, expanding the driver’s field of vision by pivoting up to 15 degrees as the steering wheel is turned or embedded sensors detect a change in the environment. However, the technology is complicated and may vary between auto manufacturers.
On a Lexus IS250, how do you turn the headlights 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.
What is Toyota’s AFS?
To enhance vision while cornering at night, intelligent AFS reroutes low-beam light units in line with the steering angle and vehicle speed.
Bits of Knowledge
Depending on the cornering direction and the nation in which you reside, the angle of the irradiation axis can be altered. These variations exist because, for right-hand drive vehicles, the left light is designed to illuminate a wider area than the right light. Toyota has therefore made the left light less movable to prevent blinding oncoming motorists.
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.
Are Lexus’ headlights adaptive?
An major innovation is highlighted in the news releases from Lexus Global, Europe, and even Australia for the 2020 RX refresh: the inclusion of the first-ever BladeScan Type Adaptive High-beam System (AHS).
This is how it goes:
In a first for the automotive industry, BladeScan technology has been added to Lexus’ innovative LED Adaptive High-beam System (AHS) to improve nighttime driving safety. A lens receives light from a lens that is delivered to two blade mirrors that are spinning quickly from an LED source. This light illuminates the road in front of you. By coordinating the rotation of the blade mirrors with the on/off of the headlights, the dispersion of light is accurately regulated.
As a result, RX drivers can see dimly lit areas like road shoulders and spot pedestrians and traffic signs far earlier without compromising their overall visibility or blinding cars going the other way. With BladeScan technology, pedestrian identification at night has increased to 56 meters (184 feet) in front of the Lexus, up from 32 meters (105 feet) with the prior system (Array-type AHS).
The aforementioned picture plus this all-too-brief film serve to better demonstrate the concept:
However, why aren’t the United States and Canada using this innovative technology?
You can hold the 1967 law governing vehicle headlights, U.S. Federal Motor Vehicle Safety Standard No. 108, responsible. The main problem with the BladeScan AHS is that there is only room for one low beam and one high beam option. No intermediate settings are allowed, using both low and high beams at once is prohibited, and the low-beam headlight candlepower restrictions are insufficient.
FMVSS-108 has previously undergone revisions and updates, however the procedure moves slowly and necessitates a plethora of research, assessments, official evaluations, public hearings, comment periods, and input from interested parties.
Toyota, the parent company of Lexus, took the initiative to legalize fully adaptive headlights in the US back in 2013, and Audi and BMW followed suit in 2016 and 2017, respectively. The problem is still unresolved, as accounts from October 2018 and April 2019 serve as a reminder.
But why, despite having more tolerant headlight laws, does Canada have to deal with this American bureaucracy? A hunch would be that the Canadian facility in Cambridge, Ontario will serve North America while the Kyushu plant in Japan will produce Lexus RXs with BladeScan headlights.
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 parking brake is applied, a manual gearbox car’s lights won’t turn on.
- If the transmission is in park, your daytime running lights won’t switch on.
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.
What causes my headlights to rise and fall?
For instance, faulty connections can cause the motor to continuously move the beams up and down. Alternatively, a headlight beam will always level off at the lowest point and remain there. A manual adjustment or a different setting may occasionally be helpful, but these are not long-term fixes and result in a reduction in lighting quality.
How bright are your headlights at night?
When it is dark enough to not be able to see enough of the road ahead to drive safely, high beam headlights should be utilized.
Even the most seasoned drivers may find nighttime low visibility frightening. Why is nighttime driving riskier? A driver’s acute visionwhich includes depth perception, color identification, and peripheral visionis responsible for 90% of their reactions, all of which are significantly impaired at night. Headlights with high beams shine at an angle, illuminating the road 350400 feet in front of the vehicle, or nearly twice as far as low beams. (Remember that 100 feet per second is equal to 68 miles per hour. Low lights may only offer you a few seconds to react to a hazard when driving at highway speeds at night.)

High lights can help keep you safe but, if used improperly, they can also put other drivers in risk. Whenever there is a chance that you might blind other drivers, you are required by law in every state to lower your high beam headlights. In general, high beam headlights cannot be utilized within 500 feet of an approaching vehicle or within 200 to 300 feet of a vehicle you are following. The exact distance varies from state to state.
Do adaptive headlights merit the expense?
Do adaptable headlights make financial sense? According to the Insurance Institute for Highway Safety, adaptive headlights could contribute to the avoidance of up to 90% of nighttime curve crashes. For the cars that have them, insurance firms observe a 510% decrease in crashes.
