The problem with red dash lights is they are very hard to see when you have oncoming traffic, like on a two lane road. If your eyes see bright white light, they take a long time to adjust to red light. Red light is supposed to keep more of your "night vision", but the first oncoming car ruins any "night vision" you had.
My '86 Mustang had red dash lights and sometimes I could not read the speedo, staring right at it... and that was with 23 years old eyes. I'm sure it would be even harder with 53 year old eyes.
Car MFG's went away from red dash lights in the late 80's because of complaints.
