Life Paint
It doesn't matter if you're walking, running, or riding a bike — it's a lot easier for cars to see you after dark if you're wearing something reflective. With Life Paint, that can be pretty much whatever you want to wear. This water-based reflective spray is invisible by daylight, yet glows brightly when hit with the beam of a car's headlights. It works best on textile materials, whether it's shoes, a jacket, or a hat, lasts for over a week during normal use, and washes off, leaving whatever you sprayed it on just as it was.
