Quoting Larry Cad:"Are those the lights that always blind me when coming toward me? Always wonder what kind of death wish the driver has, that he wants to blind me coming toward him such that I may accidentally drift over into his lane and hit him head on!
Just curious."
DRLs are headlights at 1/2 power that are automagically on whenever your engine is running, and you are not in Park. They are one of the best safety features and I won't own a vehicle without them. They keep those left turners from claiming they never saw you when they turn in front of you and you end up t-boning them.
