These signs are commonly used for advertising and artistic displays due to their vibrant colors and visibility, especially at night.
Typically, neon gas or LEDs are used in illuminated signs to create bright and vibrant lighting effects. Neon gas is known for its distinctive glow in various colors, while LEDs offer energy efficiency and durability. Both elements are commonly used in signage due to their effectiveness in attracting attention.

Neon gas is a colorless odorless gas that fills tubes that are often used in electrical advertising signs.
Usually a gas, neon is also available as a pressurized liquid. Neon gas is used in red lights used as exit signs or illuminated advertising signs, TV picture tubes, lasers, and voltage testers. Liquid neon is used as a refrigerant in cryogenics.
