Selectively illuminable phosphor devices (10, 110) are provided which include a flexible substrate (12, 122) having a phosphor material layer (28) on one face thereof and a conductive layer (34) on the opposite face. A pair of electrical leads (14, 16) are provided for application of a high-voltage, low-amperage operating current serving to excite and illuminate the phosphor material, giving a bright, visible light. The operating current is provided by means of a source of electrical power such as a battery together with appropriate electrical circuitry (58) including a step-up transformer (78) giving the desired high-voltage, low-amperage excitation current.
