My head light indicator remains constantly on now. I've always had it set for auto. It's still auto now, but my head light indicator is always on now. In the past when I went into a tunnel or parking structure, the head lights would turn on automatically. If I toggle it off and then to auto, it doesn't seem to change anything. Today its sunny day in SoCal. If i switch it to "Off" head lights turn off. I switch it to "Auto" the head lights completely turn on. Its not the day time running light like it's been in the past.
