NEON signs, or other gas tube signs, do not typically LEAK. They are under vacuum, and if cracked, will suck in air, making them unable to properly light up, or not light at all.
After (usually) years of use, sometimes DECADES, the gas in a neon tube will do something that is called "clean up". This refers to the action in a luminous tube where the atoms of gas apparantly combine chemically with the electrode metal. Sometimes if you look closely at an aged tube, you can see a shiny metal sputtering on the glass wall right around the electrode. The atoms strike the electrode at high speed, and this striking action may very well serve to break down the atomic structure of the gas and metal atoms. It may be possible that the atoms of gas are able to combine chemically with the glass atoms too... as there are electrodeless lamps that also have a finite life.
In most all cases, the gas pressure of luminous glass lamps gradually decreases until the power supply can no longer light the tube.
In my industry (neon signs) many neon tubes come back to the shop after decades of use. They no longer light up on a standard transformer... but when hooked up to a very large 22,500 volt neon bombarder, they will light up for a few brief moments (sometimes minutes) until the last of the gas is eliminated. The electrodes often heat up very red due to the low gas pressure, which allows the atoms to pick up more speed when bouncing around. This increased speed can actually crack a corner or double back area of a neon tube... often times puncturing a fine hole in it.

Is neon gas in a neon sign an element?
Neon from a neon sign is an element. It has the symbol Ne and is in group 18 which is noble gasses.

What is involved with installing a neon open sign for a store?
The installation of a neon 'open' sign for a store can be as simple as mounting it to a window and plugging it in. But be careful! The neon sign is made from glass and is very fragile!

What is the difference between an electronic sign and a neon sign?
Neon signs, by definition, must contain the element neon, which glows when an electric current passes through it (although the term is sometimes more broadly applied to signs containing other nobel gasses). An electric sign is simply any sign that requires electricity. The difference between an electronic sign and a neon sign is electric sign requires electricity to function. On the other hand, neon sign reflects other lights to work.
What is the regular configuration of a neon beer sign?
The configuration of a neon beer sign depends on the size of the sign. The standard neon beer sign uses less power than a 75 watt light bulb. The average neon beer sign uses 120 volt electric plugs and measure roughly 24 by 17 inches.
Is a glowing neon sign a physical change?
Yes, a glowing neon sign represents a physical change because the neon gas inside the sign undergoes a change in energy state to emit light. This change is reversible and does not alter the chemical composition of the neon gas.
What is a sign lighting gas?

When was Born Under a Bad Neon Sign created?
Born Under a Bad Neon Sign was created on 2006-03-29.
Is neon gas in a neon sign a compound?
No, neon gas in a neon sign is not a compound. Neon gas is an element, a noble gas with the chemical symbol Ne and atomic number 10. It is used in neon signs because it emits a bright red-orange light when electricity passes through it.
