Neon is used for advertising sign
It sounds like you are referring to "neon" signs. About 1/3 of all "neon" signs actually use tubes filled with very low pressure neon. The rest use other noble gases like helium, argon, krypton, and xenon - often with something like a minute amount of mercury added and a phosphor coating to the glass so that the resulting UV light produced when the gas is electrified can be converted to other colors by the phosphor coating (which fluoresces when bombarded by the UV).
Neon lights are an interesting thing. They provide years and years of service without ever burning out. They are made from the noble gases, so they are completely inert. They are capable of passing an electrical current though, and by doing this it provides an interesting colour/ appearance, depending on what gas is used/what additives are involved. They may be used either for their longevity or their bright colours, as they attract the eye.

Its mostly Argon and a small amount of mercury. Its the main ingredients inside a flourescent lightbulb, which are used to light up billboards and highway signs. See the related link for more information on flourescent bulbs.
The noble gas most commonly used in signs is neon. Neon gas is used to produce bright, vibrant colors in neon signs when an electric current passes through it.
If you're referring to neon signs, the gas used is either neon, or argon (used with mercury). Fluorescent lights use the same principle as neon signs.
No, helium is not used in neon signs. Neon signs are filled with neon gas, which produces the iconic red glow when an electric current is passed through it. Helium is a colorless and odorless gas often used for filling balloons and as a coolant in some applications.
The gas used is neon.

Neon gas is used in neon signs, which are commonly seen in advertising and signage. Neon is also used in certain types of lighting, such as neon lamps and plasma discharge lighting. Additionally, neon is used in cryogenic applications and as a coolant in certain high-voltage applications due to its ability to remain gaseous at extremely low temperatures.

The gas commonly used to make yellow-green neon signs is neon gas. When an electrical current passes through neon gas inside a sealed glass tube, it emits a bright yellow-green light.
