So, just finished reading an article on WaPo about fireflies/lightening bugs and got me thinking further… Car headlights suck. They mess up our night vision when we pass another dickhead running white/blue lights. We mess up the habit(at) of many animals/bugs. So why not red lights? My hiking/camping headlamp has a red light option, which is the only function I use, and I can see fine. Why the FUCK do we still have these ungodly bright white/blue lights?
Because red light are used for tail lights, which you also see when driving. Different light colors allow you to tell if you are looking at the rear or front of the car.
Also, we need to be able to read and recognize traffic signs, and those are often color-coded, red having a very important meaning. With red head-lamps, all traffic signs would be red-and-black at night, great !
