I know a guy who is color-blind and can distinguish traffic lights 
without problems because of their position either vertically or 
horizontally. He said the only time it becomes a problem is when there 
is a single flashing light (either red for stop or yellow for caution). 
Even though he guesses correctly most of the time, when someone else is 
in the car, he always asks the color of the light. When he is alone, he 
just takes extra precaution to slow down early in case he does have to stop.

This may be old news, but I just found a fantastic web site 
color-blindness simulator linked from the WaSP website. I've previously 
used VisCheck and like this new one *much* better.

Good luck,
