Rarely does a neon gas filled sign go dim. If so, it is usually a problem with a neon transformer not being able to fully light up the sign. If the transformer is magnetically inductive, it will flash or "flicker" the neon tube. If the transformer is electronic/high frequency, it may get weak and dim it's output. Electronic Transformers generate their output power by modulating their output very very fast, creating high frequency waveforms (almost like a radio antenna) that make the gas molecules dance around.
Most commonly, an ARGON filled neon tube will go dim, especially in cold weather. The Mercury that is used in conjunction with the Argon fill gas condenses from a gaseous state, back into little tiny droplets. When this happens, the ultraviolet light that the mercury produces is no longer emitting, and just the weak lavender-colored Argon lights up. Without the mercury vapor, the phosphore coating on the inside of the neon tube will not properly light up.
So, the root cause of a dim neon sign (peerhaps more fittingly called an ARGON-MERCURY SIGN, but nobody ever makes the distinction) is missing or condensed mercury.
I can often remove a dimmed out tube from a sign, tumble the mercury around inside by rotating it in all different directions (especially important to get some of the mercury pellets into both of the electrodes - hopefully wetting the outside of the electrode shell), and re-light up the tube. By getting the mercury into both electrode ends, the mercury will heat up, vaporize, and distribute thruought the tube... making it bright again. this can take hours and must be left on in a warmer environment.
Keep in mind ALL phosphore coated neon tubes, when used with Argon/Mercury (herein after abbreviated to Hg) and even sometimes Neon gas, will depreciate their output due to the phosphores having a limited lifespan. Wiki "halflife".
Also... be aware that many electronic transformers condense the Hg by virtue of an unbalanced waveform in their output. If there is a DC component in the AC wave, that bias can actually draw the Hg to one side of a tube, making a tube bright on one side and dim on the other. This normally does not happen with magnetic/exterior neon transformers.
NEON USES HIGH VOLTAGE AND CAN BE DANGEROUS. NEVER HOLD A NEON TUBE WHEN IT IS PLUGGED IN UNLESS YOU ARE VERY EXPERIENCED AT DOING SO AND ARE AWARE OF THE SHOCK DANGERS. IF YOU DO NOT PROPERLY WIRE A NEON SIGN IT CAN EASILY START A FIRE!!!!

How do the wavelength and frequency of an X-ray compare with those of the red light from a neon sign?
The wavelength of an X-ray is much shorter than the wavelength of a red light from a neon sign. The frequency is much longer in an X-ray than the frequency of a red light from a neon sign.
Why does a ray of light within a neon sign bend when a magnet is held up to it?
It is because of the impurities within the neon plasma are attracted to the magnet.

Electric discharge

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 a lighted sign?
Neon
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.
