Abstract: A portable, durable and rugged hand-held lighting device particularly useful as a safety flare or illumination device is described. This device utilizes a rare gas containing illumination source (e.g. a glass tube containing the rare gas) and is particularly useful in projecting light during darkness or in fog. The light source may be any of the conventional rare gas materials but neon is preferred. A fluorescent material coating the inside of the glass tube may be used enhance the output of the light from other rare gasses. The power supply for this unit may be replaceable or rechargeable batteries or the device may be connected to a permanent DC or AC power supply to enhance the life thereof. A transformer is used to increase the electrical power supply from the power supply to the glass tube and is required in order to get the high intensity light output afforded by the use of rare gas illuminating devices.
