The reason why the INSTRUMENT lights might be red on aircraft is so that light pollution in the cockpit doesn't interfere with the pilot's ability to see outside (a) when ambient light requires wide-open pupils and (b) so they can see clearly when using their WHITE lights to land and take off.

If red was a solution of greater visibility, do you not think the motor vehicle industry would have put something in place before now.

Oh, and the definition of a WHITE light for headlamps/lights on vehicles, including bicycles, has always bemused me in terms of the BLUE light cast by LEDs... leading me to think that technically they could be interpreted as being illegal.
