for colorblind people? l dont understand colorblindness very much but doesnt it cause problems with distinguishing between red and green? So wouldnt that be a problem?

lol I am sorry if this is a very stupid question but l was just wondering...
Yeah l thought that, but for some reason l thought that wouldnt work in the day time. But now that l think about it, l think you're right.

Hmm.. It depends on how dark and bright the green and red are. If the red is dark and the Green is lighter, than no- and also because someone will tell them when they are learning to drive probably that the highest light means ''Stop'' and the lowest light means ''Go.''
