well lets just agree we both have different views but when you research it there is a difference.

In order to get both the main beam and dipped beam in one bulb, reflectors may be added to the headlight. When the driver switches between main and dipped beam headlights, the reflectors adjust the angle of the light. Some bi-xenon headlights use shields instead of reflectors. These shields block light when dipped beams are in use. They lift up to allow more light for the main beams when needed.

And this is exactly the solution used in every E85 with xenons.

This is the projector used in the Z4, the Hella E55 unit:


You can see the shutter and the actuator solenoid below it.

2003 3.0i Z4. Bi-xenon can be enabled via coding. confirmed that all variants of this car has this, but it was only enabled for the FL?

hope this clears out any confusion for future readers
