I keep the high beam on at all times durring the day......
At night I use high/low in the prescribed by law mannor.
I was once pulled over by an Irrate state trooper for not dimming my light. And was required to perform "stupid human tricks" (road side sobriaty test). Had worked late and stopped for one beer. Passed the test no prob but was no fun at all. Well I'm sure passing motorists were ammused and the cop seemed to be enjoying it. So yes I dim my headlight for oncomming traffic.....thank you.
