If you’ve ever seen a traffic light with blue light instead of green, you don’t have visions, they change for…
A traffic light with blue lights? No, this is not fiction, it’s all true! Oh well, There are traffic lights where we all have blue light instead of green light.
This peculiarity is more widespread than we think and could become even more widespread in the coming years. Some people think that can mislead and confuse driversbut in reality it is exactly the opposite.
With all changes to traffic rules In fact, it is not surprising to see other novelties that are in some ways absurdeven if not everyone agrees with the government’s recent decisions.
Lately we’ve been hearing all sorts of things, change more, change less, It is becoming increasingly difficult to keep up to date with the latest decisions made by institutionslet alone understand anything about it.
The colors of the traffic lights
The traffic light was born in London in 1868 and consisted of a Gas lantern that rotated and changed between green and red light. The first electric traffic light was installed in Cleveland, USA in 1914, when cars were already filling the streets and a system to control traffic and prevent accidents was needed. But traffic lights, intended as a system to monitor traffic flow, were born in the railway environment much earlier.
This is where the inventor of the traffic light got his inspiration for the colors: red, yellow and green were already used for railways and even ships. Remember that even at sea, those coming from the right, i.e. the side usually marked green, have priority. But Times change and so do needs, and that’s why there is a blue light at the traffic lights.

The blue at the traffic lights
If you think that the colors of traffic lights were the same all over the world, you are very wrong. In Japan, traffic lights have a blue light next to or instead of the green one. But why this choice? The reason for this is that in the Japanese language, the colors blue and green were originally identified with the same word. To avoid confusion, when traffic lights were introduced it was decided to place the two traffic lights next to each other.
Today this combination is no longer useful because there are two different words for colors and in any case in 1973 the Japanese government decided that from that moment on traffic lights should be made with green light, albeit in some areas You can still see old traffic lights that have both traffic lights.
