Have you noticed before how it is more difficult make out signs illuminated with blue LEDs and on occasion how blue LED aerodrome lighting can appear somewhat fuzzy? I found an interesting article here (http://texyt.com/bright+blue+leds+annoyance+health+risks), explaining the physiological difficulties which blue light presents. Should this be a Certification Standard issue?
