What does it mean when the AFL light is on?

[VanJosiah]

AFL light on indicates a malfunction in the Adaptive Front Lighting System. AFL stands for Adaptive Front Light. Possible causes of the malfunction include a stuck internal steering mechanism in the headlight, damaged drive motor, faulty AFL steering sensor, or loose/disconnected wiring connectors. The Adaptive Front Lighting System consists of four main components: sensors, ECU, headlight control system, and headlamps. Adaptive front headlights, also known as auto-sensing headlights, are essentially headlights equipped with a photosensitive control system. The central intelligent control box determines changes in light intensity via light sensors and controls the automatic activation or deactivation of the headlights accordingly. Adaptive front headlights allow drivers to avoid the process of manually searching for the switch when headlights are needed, while also preventing drivers from forgetting to turn on the headlights during nighttime or in poor lighting conditions, thereby enhancing driving safety.
