Abstract
Abstract A phosphorescent vehicle part identification accessory comprising an article of molded plastic having formed therewith a phosphorescent compound adapted for glowing for a period of time following exposure to light energy. The phosphorescent article is secured to the vehicle in a location thereon for receiving illumination from other vehicles and external light sources and providing a decaying glow therefrom. The phosphorescent article may comprise a vehicle wheel valve stem cap, a strip, or a tab adapted for positioning about a vehicle keyhole.
