Researchers See the Light To Reducing Bird Strikes
In the tests, birds consistently avoided LED lights with peaks at 470 and 630 nanometers, which appear blue and red to the human eye.

Researchers at Purdue University believe that adding externally mounted red and blue LED lights to aircraft might one day help reduce midairs with birds. They found that LED lights in these color spectrums lead some birds in the opposite direction, according to a study published yesterday.
