Yes commen courtesy is required when on the road and a good driver is aware of on coming traffic. So the difference is really are you a driver or just someone who is clueless on the road. My commute is in the early mourning in rural central Georgia, I see a dead deer at least twice a week and have sent four Bambi's to Deer Heaven. I would guess that each one cost about $1200 in damage not to mention the time in the body shop.
So since 1973 when a bolted on a set of Cibie's 195's with 100watt bulbs on my Capri I have had powerful head lights on every car I have owned. I believe excellent lighting is a safety factor and decrease the chance of an accident. Sticking to light standards that were established in the 1940's is not a good idea. I have never been stopped because of my lights, and try to be extremely conscious of my lights anytime I am driving at night. Three of the deer I hit I was not going over fifty when they ran into the road. Twice I feel the extra light gave me an extra few seconds to get on the brakes, still I hit them but at a cheaper speed!
And if you are one of those A-Holes who like to drive around with your brights on, 400 watts of light will get your attention real fast.
