In this patent a self-luminescent article is described which comprises an opaque tubular shroud and a chemiluminescent device which comprises a light transmitting tubular body containing a chemiluminescent material, the chemiluminescent device being in telescopic relationship with the shroud and the shroud being provided with a stop means which prevents the complete removal of the chemiluminescent device from the shroud. The shroud permits the chemiluminescent device to be concealed while in operation and prevents the premature activation thereof.
