Bixenons use a flapper inside that changes from low beam to high beam. This works by pushing the lever forward.

The inner reflector bowl is used as “flash to pass” feature which uses the halogon bulb to “flash” people.

I prefer this way since honking sometimes comes off as rude and use flash to pass by pulling the lever towards you.

Another car I have only has bixenons and people can’t tell I’m flashing them.
