I have the head lights switch on auto. I have noticed the lights do not come on until it is almost dark. My car has the same auto feature and it comes on much earlier at dusk. Is there an adjustment that I can do to make them switch on earlier on my F350?

 

This hasn't been my experience. The sensor is the little square ish pyramid on the dash in the centre, close to the windshield. I have noticed sometimes even driving into a shady area, the headlights will come on, because my displays change to lower light. I would keep an eye on it to make sure it's working properly. It's possible your dealer can check it out and perhaps something in your trucks IDS can be adjusted.
