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.
Brief History of Neon. Over the last 150 years the luminous tube industry has evolved from the simple laboratory experiments in the second half of the 19th century to an industry of world wide proportions. The first luminous tubes did not use neon or any other rare gas. In the late 1800 s scientist developed reliable and somewhat safe high voltage supplies and began running high voltages through many things to observe what would happen.
