Safety is a primary consideration as children dart about on their trick or treat movements. They can be into a street before being noticed. And, when one person is responsible for keeping tabs on several children all at once that person cannot be looking in every direction. So, it is up to the adult to make the child visible before starting out.
When I was a child we carried flashlights and had lights in our pumpkins. This was the best option available, but the lights were all directional. We were much less visible from behind, and even from the sides. Only our constant movement redirected the flashlights in multiple directions. But were we really safe? Perhaps we survived because automobiles were scarce, so when we did something reckless there was no encounter with a motor vehicle.
