Comment on Front Brake Lights Could Drastically Diminish Road Accident Rates

  A lot of colorblind people can tell the difference between red-green and white.

  They just percieve red-green as the same.

    Colorblind person here. If we’re talking about limited visibility differentiation of front and back, the color of light is way less noticeable than whether we’re looking at headlights or not (based on intensity). There would be no issue telling whether we’re looking at a front brake light or a back brake light so long as the front brake light has headlights around it.

  It’s doesn’t matter, since the absence or presence of light would still be perceived by colour blind people. It doesn’t change how they would drive, as they are already driving with the knowledge of colour blindness in mind when looking at tail lights.

  Tail lights being red is fine if you live with the most common forms of colorblindness which fall into what we call “red-green colorblind.” It is still a different color than headlights.

  Now put those same red-green lights on the front, and we have a problem.

    They could use traffic light green. There’s not any problems identifying those even in places with the lights mounted horizontally. There’s enough difference in saturation you can tell the difference even with colorblindness.

    But why? Again, the perception would be absence or presence of light on a standardized indicator.

    FYI signal lights are much more strictly regulated I. Europe, such as position, colour, shape and strength.
