LED headlight
The Body Domain Controller (BDC) is the master control unit for the exterior lights. That means: All the lighting functions are controlled by the Body Domain Controller (BDC).
Depending on the light function, multiple LEDs are usually bundled and switched together in so-called LED modules.
Depending on the selected lighting function, the corresponding components are activated upon request of the Body Domain Controller (BDC) via the Frontal Light Electronics Left (FLEL) and the Frontal Light Electronics Right (FLER).
For automatic headlight beam throw adjustment the LED headlight is vertically adjustable via a servomotor.
The following illustration shows the left LED headlight using the example of I01.
