Approximately 1.19 million traffic lights were deployed across Japan as of March, 2006. Incandescent lamps have long been used as light sources for traffic lights, but recently they are being replaced by LED elements. Advantages of using an LED as a light source for traffic lights include energy saving, long life, and improved safety by preventing pseudo-emission. This article estimates the CO_2 reduction effect under the current trend towards LED deployment, and introduces our future plans regarding this matter.
