Hello my friend @donkeypong how are you doing? happy New Year for you

Curious theme and also educational, the traffic signals are as important as each created thing, who knows where those people are born with those thoughts of creating things to me I could not imagine creating a traffic signal, a letter, etc.
I think the developed countries have that good that traffic signals are met and you can find them in different ways, I believe that today without traffic signals this would be a disaster
