red guage cluster needles how to..

red light doesn't stimulate the rods in your eyes, other wavelangths stimulate both cones and rods. Rods are used for night vision, so when you look at red wavelangth light it doesn't mess it up. So its good to have red instrements because your eyes don't have to adjust to them during the night. that's the point.

To me the red needles would be a lot darker than the than the white so they would stand out less. But that's just me....
