Neon mostly.
neon, i think. :)

It is neon
Neon
Neon is a noble gas and is inert (or generally unreactive). It is the tenth element on the periodic table. It is an atom.A more in-depth scope of neon:It has the electron configuration of [He]2s22p6. This gives Neon a full electron shell of the highest energy level. This makes neon exceptionally stable as a gas.In nature, neon is a monoatomic gas. This means it is found usually not bonded with another neon atom like oxygen (O2) and other gases.Neon's spectra that it gives off when excited (by electrons becoming more energized) is seen as a bright light. Its general color in a cathode tube is seen as bright red to reddish-orange. This makes it useful in neon signs (neon signs actually contain different inert gases responding to energized electrons giving off different colors).
All the noble gasses, plus mercury vapor.
Neon was discovered in the late 1800's. I do not recall the scientist who discovered it (I believe there were two). It is a rare gas found in the atmosphere and is produced as a byproduct when creating liquid air. As a liquid itself, it is better then liquid helium or hydrogen when used as a cryogenic but it is more expensive. it is used mostly in lasers and in making signs since it will glow when electricity is applied to the gas.

Neon is used for bright flashing signs such as advertising signs.
Neon
If the color is red, the element is neon, a noble gas.
The most common use of neon is in advertising signs where it produces a bright reddish-orange colour.
Different gases from the Noble Gas series give different colours. These include Neon, Argon, Helium, Krypton, Xenon. See Wikipedia article 'Neon Sign', there are coloured pictures in the article.
Neon signs are one of the most effective forms of advertising for bussiness.
Neon is used for advertising sign
In order for signs to be most effective, they need to have bright colors.
Neon
covers establishments primarily engaged in manufacturing electrical, mechanical, cutout, or plate signs and advertising displays, including neon signs and advertising specialties.
Digital signs are effective when advertising. Mainly because when someone sees the digital signs they change and you get to see more than one advertisement.Other companies can come together on one sign.
mostly neon!
