Default Takes long time to turn on headlights while in auto mode

I just noticed my automatic headlights turn on only around 10 seconds after driving into dimmed car garage, while for other cars it takes 2-3 seconds.

Do you have the same problem with your car? The light sensor doesn’t look damaged or broken.

10 seconds is a long time?

I had the same issue with my 2021 RX. In the setup menu you can make your lights go on in less dim light. Basically, your headlights will go on sooner as night approaches. Maybe this will fix the issue. I've attached a YouTube video which explains this in better detail:
