A substantial majority of the population, with colour blindless, have trouble seeing the red area of the visual spectrum. If this product were to be implemented as is, people with red-green colour blindness WOULD NOT see the light indicators. However, only a small percentage of people experience blue-yellow colour blindness, and when they do, it translates to white light in their visual spectrum.

To ensure success for this product, a more suitable option would be to use yellow indicators instead of red, to ensure drivers don’t suddenly crush cyclists under their vehicles because they can’t see the warning lights!
