I have an '03 Legacy L SE Wagon which comes with factory installed driving ("fog") lights (although smaller than those on OBW). I've noticed that when I switch my headlamps to high beam, the fog lights switch out, and come back on when I dip them. Any one know why they behave like this ?
It may just be my perception, but to me their aim fills in the immediate foreground that the headlamps on either setting don't cover, which is nice on Connecticut backroads to illuminate suicidal opossums or the like which amble on to the road just in front of you!
