The traffic light is another Filipino innovation. It was Teodoro Cruz who came up with the idea when he noticed during Christmas time how his fellow Filipinos would always stop their cars as they enjoyed the different colors of the Christmas lanterns along the roads. He then created the traffic light system using the colors of the Philippine flag. The Americans changed the blue into green, even though colorblind people can’t distinguish between red and green. Research the roots of traffic lights; the Philippines is not mentioned.
