Have you ever had trouble
Have you ever had trouble telling which lamp on a traffic signal is activated? Not knowing whether a light is red or green can be very dangerous, and it often happens when the sun is shining on a traffic signal. On this edition of J-Innovators, we meet the Takumi, or innovator, behind a revolutionary new kind of traffic signal that solves this problem. Traffic signals can be difficult to see when the sun's rays reflect on the mirrors inside a signal's lights. To prevent this from happening, the Takumi had to overcome two hurdles: preventing sunlight from reflecting off the lights, and ensuring that only the proper light appears illuminated to the human eye. Join us as reporter Michelle Yamamoto looks into the technology behind this bright new innovation!
