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.
Of all the rare gases, the discharge of neon is the most intense at ordinary voltages and currents. Although neon advertising signs account for the bulk of its use, neon also functions in high-voltage indicators, lightning arrestors, wave meter tubes, and TV tubes. Neon and helium are used in making gas lasers.
