high beams and low beams location

What is your question?

I want to know which bulb is the low beam and which is the high beam because I turn my switch just once and it turns on the the two inside lights which are not bright at all then I turn it once more and the outside light comes on once which I believe is the low beam and when I turn on my high beam the 2 inside ones that were not bright at all turn on really bright this time. So are the low beams and high beams separate or together is a main question and if they are together do they go on the outside part of my headlights lamps ? This is all so confusing hope someone can help please
