Abstract
A phosphorescent assembly for humidifiers and vaporizers that enables the vaporizers and humidifiers to be easily seen in dark or dimly lit areas. The presently preferred embodiment of the invention provides for the water reservoir in both the humidifiers and the vaporizers to be blow-molded from a phosphorescent, plastic material that will be luminescent for several hours after being exposed to radiation within the light frequency spectrum.
