The Chinese for traffic light is red-green-light (hónglǜdēng).

  Interesting. It's 신호등(shin ho deung) and 信号灯(shin go tou) in Korea and Japan. Both literally meaning signal(信号, 신호) light(등, 灯), so I would have thought Chinese would use something similiar (I can see 灯 is being used). I wonder why that happened. Maybe because red is an auspicious color? Or maybe because the word may have originated from Japan and they wanted a different word? or maybe simply because that's what people started to call it and it stuck?
