It is amazing to me that colors of instrument readouts is not regulated, when the research is extremely clear that red and orange (and yellow) are much better for night vision than white, blue and green. Add to that the huge screens in most cars these days and you have a recipe for night blindness caused by just looking at your infotainment screen for a second and not seeing a pedestrian due to the ghost image left on your retina.

I get the same thing in my city with digital billboards. I can't believe it's legal for them to show pure white backgrounds at night, especially flipping from a mostly dark background. Driving down the road when suddenly a massive billboard floods your eyes with bright-as-day pure white light... not a good thing.

That one is usually regulated at the city level. You might talk to your city council. There are many, many good reasons to disallow that kind of lighting, it could be it just hasn't been on your city's radar yet.

Do you have any link to the research you're reffering to ? I looked into this a while ago when wondering why my headlamp had red ligths, and people seemed to advocate for a dim green light (eg. http://stlplaces.com/night_vision_red_myth/), but I'm struggling to find any research article backing this

And the brighter headlights on other cars likely cause your pupils to narrow, allowing less light into your eyes, so you feel like you need brighter headlights.

Until the 90's the standard color for headlights in France was yellow, not white. That was so much easier on the eyes when driving at night (and also safer in foggy conditions).

Yes! I really miss my 900's night mode button which would disable everything but the speedometer. I would call that "stealth mode" even though towards the end of its life it was one of the loudest cars on the road due to a bad muffler.

There was some real forethought in the design and layout of the cars in general but the dashboard display is perfect. I wonder if it's true when people say they took elements from the jet aircraft they made.
