Headlight positive and negative wires?

[SiDaBa]

Was just wondering which wire was which for the dipped beam bulb (H7) and for the9n headlight illiterate the bigger circle! One's brown and one's red. Sorry if these are standard electrics that normal people understand but i'm electrical colour blind

Nothing that a voltimeter can't resolve. But as far as logic goes the red must be the positive and the brown the negative (mass or earth).
