I don't think any one gas does all those things.
BUT
iodine and bromine halogens are used in bulbs
helium in weather balloons
and neon in neon signs of course

For regular light bulbs Argon is used to provide slight pressure in the bulb.
Weather baloons use Helium because it is lighter than air.
Neon signs use the other inert gases as well as Neon. Helium, Neon, Argon and Xenon.

Electric lamps - neon, xenon
Weather balloons - helium
Neon signboards - He, Ne, Ar, Kr, Xe
Rn is radio active and therefore dangerous.
Hope this helps :-)

In electric lamps--------->Xenon(argon in case of a bulb)
Weather Baloons--------->Helium(being second lightest element)(hydrogen is avoided as it is inflamable)
Neon Signboards-------->You are yourself saying NEON signboards

Air or helium are the usual options.
