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 signs that use an argon/mercury gas mixture emit a good deal of ultraviolet light. When this light is absorbed by a fluorescent coating, preferably inside the tube, the coating (called a phosphor) glows with its own color.
