Neon can last decades. In practical terms the normal expected life span is between 8 to 15 years. Neon can be repaired and recharged as long as the tubing is not cracked/broken.
Neon lamps and neon signage (most of which is not neon based these days) are also low-pressure gas-filled tubes. Specialized historic low-pressure gas-filled tube devices include the Nixie tube (used to display numerals) and the Decatron (used to count or divide pulses, with display as a secondary function). Xenon flash lamps are gas-filled tubes used in cameras and strobe lights to produce bright flashes of light.
