An ultraviolet light emitting diode flashlight is contained within a housing having a pen tip extending from the housing and an ink or dye reservoir in fluid communication with the pen tip. The ultraviolet light emitting diode flashlight within the housing emits light capable of inducing fluorescence in the ink or dye. A switch assembly completes an electrical circuit between a light emitting diode and a battery to activate the flashlight. A writing system package includes at least two of: a neon or pastel colored writing surface, a security pen having an ink or dye that fluoresces in the visible portion of the light spectrum upon exposure to ultraviolet light, and an ultraviolet light emitting diode flashlight.
