Traffic Light

genius

You can add a diffusing lens to blend the colors, ie the read/green combo would look more natural yellow and possibly superimpose a visual pattern for color blind people, eg. an X pattern (using appropriate LEDS turned on) that would be visible to them

Great Project!

awesome

this is genius

Actually there is a reason why there are three lights. the problem is in the sequence, its not the same order when it goes from green to red and from red to green. Take a closer look. One sequence involves yellow light to be lit on its own, and other sequence combines yellow with other color at the same time. (otherways you would have no clue if the green light or red is coming after the yellow, if you are at high speed reaching the traffic light..) other than that, great concept really, good thinking. Here is the thing,

Very cool in terms of design. You would have to figure out a way for color blind people to use it. I think this is one of the reasons the three light system hasn't changed.

innovative...

very nice

Sound for blind? Great design!
