816 Light Up

I was looking at the traffic in the evening light. Cars, bicycles and bikes on the road, or jets and helicopters in the sky, (and if I could see river or sea, the boats on the water alike) were all with light and their movement looked like dynamic illumination. I was just wondering it could be brilliant and beautiful if the people walking in the street were also wearing light of their own and could join the wave of lights of vehicles. They may wear light in the shoelace, or as a headlight, or anywhere they like. Light of cars moves fast, and light of people moves slowly. The imaginary vision fascinated me much. (And I guess it also contributes to the traffic safety in the night, doesn't it?)
