This invention relates to a stable, highly visible, multiple use, chemiluminescent composition of matter and aerosol system capable of articulating, communicating, displaying or marking, night-time chemiluminescent messages, in the form of written text, numerics, alpha-numerics, figures, drawings, emergency messages, trail markings, lanterns or distress calls, directly onto various substrates and surfaces, including dark or non-reflective objects and outdoor natural surfaces such as grass, trees or land. The invention functions by co-dispensing two vessels, each of which is pressurized by means of a non-flammable liquid or gaseous propellant. The chemical ingredients from each vessel are combined upon contact with the surface or by means of a mixing valve or upon attached to the actuators of each vessel, which simultaneously eject the contents of both vessels and produce a chemiluminescent aerosol spray.
