Why doesn't the inner part of BMW Angel Eyes headlights light up?

[LeFelicity]

If equipped with adaptive headlights, the inner lights will illuminate when turning. If not equipped with adaptive headlights, the inner lights are purely decorative. Angel Eyes Headlights: Refers to the yellow or other colored LED light rings surrounding the low and high beam bulbs, which look very attractive when the parking lights are on. Adaptive Headlights: Also known as automatic swiveling headlights or automatic headlamps. Adaptive headlights are abbreviated as AFS, which stands for Adaptive Front-lighting System or Intelligent Front Lighting System. The Adaptive Front-lighting System (AFS) dynamically adjusts the headlights based on the steering wheel angle, vehicle yaw rate, and driving speed to match the current turning angle. This ensures optimal illumination of the road ahead and maximum visibility for the driver, significantly enhancing driving safety in the dark. On poorly lit roads or winding routes, it expands the driver's field of vision and can provide early warning to oncoming vehicles.
