AHL: Adaptive Headlights
- > E60, E61, E63, E64, E65, E66 up to 03/2005
The AHL control unit actuates the adaptive headlights.
For safety reasons, the AHL control unit is also responsible for the automatic headlight-range adjustment. This is because: Oncoming traffic must not be dazzled by the adaptive headlights. If a headlight sticks in an unfavorable position, the AHL control unit will attempt to move this headlight down (using the stepper motors in the automatic headlight-range adjustment).
The AHL control unit is connected to the PT-CAN.
