Percy Shaw, Invention of Road lights

The invention of road lights
If there is a mist in the night it is difficult to walk on the roads. There is a danger of accidents due to which the roads of 2-5 meter are not visible. Due to the location or turn of the direction of the road direction or the maze at the intersection, the path is not properly visible. You may have noticed that the red crosses are placed on the crossroads on the axis between the center of the road and on the side of the road when they are lighted by a lightning vehicle they shine, they provide great help to drivers.

15apr1890-1sep1976

That night was a big haze. Percy was going to Bradford to his home Halifax in the car. The road was not properly known due to the thick mist. only then did they see that the trunk of the car is shining in the light of the car. He reached home with his support but in his mind, it becomes confused about how to make road traffic more secure. In the end, they got an idea and they decided to place round pieces of glazed glass in the center of the road which shines in the light. Percy named them the cat's eye. Because the cat's eye glows in the dark
