Ahuh.
Getting back on track aside from the fact that some of us do drive with out lights on for safety or to meet fleet company guidelines, you can get a kit fitted from ford where the lights are on all the time when the motor is running, and at nite you just switch them to on to illuminate the dash and make the screen go black.
So if you want your headlights on and the screen to stay grey during the day, then get the daytime light option fitted
problem solved.
