Same as clubin. If I’m in the shade when I start it up, it stays in night mode for quite awhile before it decides to change. If I start it up in the sun, it’s fine. One thing I do is just run what I call the eye brow lights. As soon as I turn those on, it goes to day mode. It does usually stay in day mode if I turn those lights off within a few minutes. If I leave the switch in that position 24/7 I don’t have an issue. At least I know they’ll turn off after I turn the key off.
