How many feet should you dim your lights when approacing a car?

Answer 1

I have been i situation in the Australian outback where you can be approaching a car for nearly an hour traveling at over 120 kmh and their high beam is already irritating. so I turn mine down when ever I see on coming traffic. and normally they do the same for me. So the right time to turn down your high beam is when you are facing oncoming traffic. any time you are blinded by oncoming traffic just flash your high beams and in the majority of cases the oncoming car will dip his lights.
