I can't speak for the DP's, but back in my flying days, we used red dash lights because they do not mess up your night vision. Once you get use to the dark, a bright light like white dash lights will lessen your night vision. Red lights do not. Something to do with rods or cones, but I have long since forgotten.

It's not so much that you are dealing with rods or cones since ALL color is viewed with cones. What helps is the placement on the visual spectrum of light that red resides on (extreme end....highest wavelength just before infrared). Since cones do NOT respond well in dim light you want a color at the far end of the spectrum unlike a color like lime-green (right in the middle). This is one of the very reasons they went to lime-green fire engines. It is VERY easy to see a lime-green fire engine at night as opposed to the traditional red. Hope that helps.
Long story short? It is softer on the eyes to give illumination at the wavelength of red

Tod,
Thanks for the pic. That's exactly what I'm axin 'bout. In your pic, you can see the red lights in the SunTrust car and the red car in the background. When watching the DP's race, the red lights are visible during daytime racing when the cars presumably don't require interior lights to see the guages and instruments.
What gives???

They are actually the cars rear lights. There is just no interior panel to prevent them from reflecting forward. I was wondering the same thing, then heard the announcers mention it once.

What? You are confused. They are simply to light up the gauges, nothing more, nothing less.

Nupe, these guys are full of it.
Those lights (only on the DP cars) are on to alert GT cars that they are coming. It is a visual aid to make the car in front of them in a different class aware of their presence.
