2013 335i headlights, do they not all turn on, when high beam or ?

When driving during day, DRL on, and use flash to pass only outside lights turn on

at night with headlight switch in A (auto) mode only outside is on

In short I cannot figure out what combination causes the inside bulbs to illuminate.

not talking about the halo's

I believe it illuminates when you are making a turn, while your headlights are on..

They are the cornering lights and they illuminate when you are turning and headlights are on. If you turn left the left one turns on and vice versa when turning right. In reverse both illuminate.

If you are in US as AHL is standard on all your models.

If you not in US, you need to have headlightt with AHL options, otherzise inside lamps will not turn on.
