The concept of a front brake light has been floating around the automotive industry for some time now. However, no vehicle manufacturer has yet embraced the idea and turned it into a reality on the
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 in Europe, such as position, colour, shape and strength.
