This only applies to certain bike with the low beam of there bike always on and the other side always off untill you turn on the high beam.
I ride all day with both them on at the same time, i think it looks better and more symmetrical.
I also hate stupid people always walking up to me telling me "hey one of your lights are out" ... i know I should just laugh at them and spit on their shoe... but after having it happen to you so many times it get kind of frustrating after a while.
well the question is
do you run your high beams on too, to make your bike look like it doesnt have noe light out?
or do not and just dont care?
