|Neon is used in gas-discharge tubes, high-voltage indicators, wave meter tubes, warning lights, lightning arrestors, radio devices, television tubes as well as in cryogenic technology. Neon and helium mixture is used in helium-neon lasers. The reddish-orange color that neon emits in neon lights is widely used to make advertising signs and is used in long tubular strips in car modification.|
Liquefied neon is commercially used as a cryogenic refrigerant in applications not requiring the lower temperature range attainable with more expensive liquid helium refrigeration. Recently it was also used as a neutral atmosphere, but then neon was replaced by less expensive argon.
