What Are Neon Signs? 

Glass tubes are bent by skilled glass artisans into precise shapes in order to make neon signs. Special machines extract all the air from the tubes, and replace it with noble gases, such as neon and argon or Helium. The neon lights are similar to billboard lights and can be observed all over the city in various sizes. Because of the lower resistance of neon gas, it emits a bright red glow and the argon light emits a less powerful effects. https://neondirect.co/
