If I drive under some trees or in the shadows, the headlights will come on and stay on for awhile even in strong daylight. They will eventually go out but seem to come on at just a hint of darkness, except for today when we experienced a rare overcast day and the headlights did not come on. I just let it do it's own thing and I don't worry about it anymore. Most cars now have DRL's so the headlights coming on during the day is not a big deal. If it annoys you, you can manually turn them off.
