A light using two (or more) electrodes in a glass tube filled with a mixture of inert gases. The most common (and the source of the name) is neon gas, which produces a red light when ionized by current flow between the electrodes. Helium, argon, and xenon are used in the mixture to produce other colors. Sometimes neon lights have a tiny amount of tritium gas added because the radioactivity pre-ionizes a little of the inert gas making it easier to start current flow to ionize the rest of the gas and produce light.
One type of neon light used in older electronic equipment that displayed numbers called a Nixie tube typically had 12 electrodes in a cylindrical glass tube: one electrode was common, ten of the electrodes were shaped like the digits 0 to 9, and the last electrode was a decimal point.

a neon number is that wheresum of digits of square of the number is equal to the number ...for example --sample input => 9sample output =>9*9 = 81,8+1=9therefore,9 is a neon numberPRACTICALLY, THERE IS NO OTHER SUCH NUMBER...ITS ONLY A THEORETICAL CONCEPT OF NEON NUMBERS !!
depending on the length of neon.. a large sign 15Kv at 60 Ma is common 1Kva
Any of the noble gases. This can be Helium, Neon, Argon, Krypton, Xenon or even Radon. Neon, for example, makes red. Krypton makes a blue colour.
Neoon is obtained from atmospheric air by distillation at low temperature.
If you mean Christmas lights; that was before. Nowadays Christmas lights are connected in parallel.
