Well Timed Closure

The Subway Signal Light is a digital sand timer that intuitively changes color from green, to amber to red, informing the passenger through passive visual clues, that the doors to the train are about to close. As far as subway safety is concerned, you can’t be too safe. Just the other day I saw a lady get caught between doors because she tried to rush through the doors at the last minute. Hopefully visual clues will help people understand better that green says go and red says STOP!
