Reply to comment by alpha417 in Daytime running lights that illuminate the road, but don't activate the tail lights should be illegal. by Lacksum

My problem is when I put my lights on auto they don’t usually switch on in twilight or on an especially overcast or low visibility day. So maybe he would have that problem with the auto setting.

a few of the more savvy brands have a threshold setting which allows more or less darkness to trigger them. each one hides it somewhere different and calls it something else in the UI. Fords used to make it easy and had a sensor, low down in the center of the dash by the windscreen, and you could just put small pieces of black electrical tape on it to make it trigger earlier. sensor was black anyway so if you were careful, you couldn't tell it was applied.
