Before high-powered headlights were invented, people had a very dangerous time driving in the dark. The first step to night safety came from a man named Percy Shaw. In 1933, Mr. Shaw almost drove off a winding road on a foggy night. What saved him? A cat, by the side of the road. Cats’ eyes reflect light very well, and the flash of light from the eyes kept him on the road. Mr. Shaw used that near-accident to invent glass reflectors for cars.
