2009 BMW 750i: Instrument Panel Color Change

January 06, 2010

bmw 750i gauge day.jpg bmw 750i gauge night.jpgJust a little observation to share with y'all. Our longterm 2009 BMW 750i's electroluminescent gauge panel makes a significant color change when you switch on the headlights.

The top photo shows the white illumination that helps the display stand out during the day. At night, there's a switch to the orange-y reddish color. The color change is purposeful -- the orange-y color has less impact on night vision than the bright white illumination. Neat trick.

Looking more closely at the pics now, I see that not only do the numerals and tickmarks switch color, but the needles, too. I wonder why the rings stay white, though.

Maybe there are other cars whose gauges make a similar transformation and I just haven't noticed. They dim when you click the headlights on, sure, but change color? Hmmm. Am I nuts? Help me out here.
