  1. EXIT WHY ARE LED EXITS SIGN GREEN & RED? Humans and animals associate bright colors with danger. Therefore, the use of red in road signals and traffic lights makes sense! LED EXIT SIGNS ARE AVAILABLE IN BOTH RED AND GREEN COLORS. IT IS SO BECAUSE: EXIT EXIT Red (color) has a longer wavelength than other colors. When looking from a distance the light reflected from a red object will always have a longer wavelength, so it will scatter before reaching the eyes. Hence, it becomes hard to spot red objects placed far away. Green (color) has a shorter wavelength and it does not scatter as much as red color. It is easier to locate green objects from a distance. Hence, using a green exit sign is also a popular way of locating an emergency exit. HOW ARE BATTERY-POWERED LED EXIT SIGNS DIFFERENT FROM OTHERS? Battery operated LED exit signs do not require any hardwiring. Installing and maintaining battery-powered LED exit signs is easier as compared with traditional variations.
