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.

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.
Neon gas is commonly used in advertising signs to produce brightly colored light. It gives off a distinct red-orange glow when an electrical current passes through it, making it popular for signage in commercial settings.
The gas used to produce red light when an electric current is passed through it is neon.
Neon gas is commonly used in lighted signs to produce a red color light. When an electrical current passes through the gas, it emits a bright red light that is ideal for creating eye-catching signs and displays.
Tubes used for light signs are often filled with a gas such as neon or argon. When an electrical current is passed through the gas, it emits light, producing the bright and colorful signs we see.
You think probably to neon (red light); but other gases can be used.
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.
Neon gas is typically used in bright flashing and advertising signs. When an electrical current is applied to neon gas in a tube, it produces a bright red light that is commonly used for eye-catching signage.
