| this isn't complicated...
during the day, with glare from the sun, or whatever it is at X brightness, but at night that same brightness could be considered a disrtaction to some, especially is you have an animated display, or things flashing on the screen. So when you turn on your headlights, it assumes it's 'dark' and dims it, so that in a dark cabin you don't have bright flashing lights to distract you, as at night, a dimmed display is still highly visable.
