Thanks MM. I found the UK version of this before and this may be a silly question, but the document uses the singular "beam". Is this just a grammatical difference or do they mean only one comes on? Here in Canada we would say "turn on your high beams" or as in the manual "...the headlamp high beams automatically turn on..." Also, I'm still not sure what A,B and C represent in this. I'll take a closer look at this today but maybe you could explain it? For some reason I'm just not getting what they represent.
