Argon Is Used.
Argon is a commonly used gas used to fill incandescent light bulbs. It increases bulb life by preventing the tungsten filaments from deteriorating too quickly. Other gasses such as helium, neon, nitrogen, and krypton are also used in lighting.

Nitrogen is the best option in normal bulbs. Because we can easily afford it easily. Argon can be also used to fill but it is costlier than N2.
Some lamps which are having color and fluoresces are having some metals with gas. Eg. NEON.

It is Argon, not Nitrogen. It might be Nitrogen, but the best answer is Argon. Argon is an Inert Gas, it does NOT react to other elements. Nitrogen is just LIGHTER than the AIR so, it is not INERT GAS, not like other Noble Gases.

Filament is made of nicrome and inert gas will not react with this. Filling a bulb with argon would be a costly process, whereas nitrogen is called inert as it does not react easily (78% nitrogen is present in our atmosphere).

Nitrogen gas is more stable and it is an inert gas that's why it cannot react with a filament of the bulb. But if a bulb uses so long time. Nitrogen gets emission gradually. That's why the electric bulb will deemed.

Modern bulbs are usually filled with a mixture of argon and nitrogen. More rarely, some bulbs are filled with pure argon, krypton or xenon.
The earliest bulbs weren't filled with any gas, but had vacuum inside.

Why would a bulb catch fire without oxygen and can even blast if it is not filled with inert nonreactive gas?
My science teacher confused me by asking this question and I answered to prevent oxidising.

Filament is made of tungsten and nichrome. If any other gas instead of noble gas or inert gas (noble gases are in the last column of the periodic table) was used, the filament would overheat and blast.

Filament is made of tungsten and when the bulb is on a lot of heat is produced so that no gaseous combustion which may lead to explosion takes place least reactive nitrogen in this case can be used.

NITROGEN is very LESS REACTIVE in nature, we know it as it is popular to reduce oxygen's activity in the air, thus, it is the perfect alternative for NEON or ARGON to be filled up in bulbs.
