Car is a 04 330 with bi zenon adaptive headlights. My low beam and high beam use the projector lens on the outside. I just push the turn stalk forward. However if I pull back on the lever for a momentary high beam the inside reflector lights come on and the projector high beams don't.
I don't understand this setup.

My 2002 does the same thing.
Thats your flash to pass light. The outside projector lights use a motorized shutter to change between low and high beams. This motor action isnt fast enough to flash the lights. It is also not noticable to other drivers in the daylight. Thats why the inner lights are used for flashing.

Is that all they are used for?
On the HID equipped cars, yes. On the Halogen equipped cars, they are used as both flash to pass and hi-beams.
Also if you have the daytime running lights coded, they will be getting about 10 v's
