today i didTraffic light I fit Traffic lights were invented because there were a lot of people ` `being injured or killed on the roads.
They prevent accidents because all the vehicles aren’t moving at the same time and there is less chance of crashing into somebody.
Did you know the first traffic light was invented in London by J P Knight in 1866. It was first erected on 9 December 1868 and was powered manually by Gas.
The first traffic lights were used for Horse Drawn Traffic. Originally traffic lights only had 2 colours - Green for Go and Red for Stop, there was no Orange light. Are traffic lights the same colours all around the World?
Hi Acein.
ReplyDeleteI like your writing about Traffic lights.
I have not read about the history of traffic lights before so I found it kind of interesting, especially that the first traffic lights were only 2 colours. Why did they develop the orange light?
Keep working hard!
