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.

In automobile lamp H4 or HS bulb is used. Which I think is filled with helium gas. Anyone can explain more about it.

Bulbs are generally filled with nitrogen for commercial purpose, argon may also be used but it may be costlier.

Incandescent light bulbs are filled with an inert gas like nitrogen, argon, or krypton - So that the filament doesn't catch fire. Early ones were a vacuum.

Tungsten is the element that is used to make bulb filaments. Best, because of its high melting point (almost 3700 K) and good resistance to electrical current.

In tenth class text book given that we use inert gases like He, Ne, Ar.

Nitrogen is used in bulbs because out of given four options it have half filled valency which makes it more stable than other options given in question.
Nitrogen have valency 1S2 2S2 2P3.. that means p orbital is half filled which is more stable than H 1S1 and oxygen 1S2 2S2 2P4... and carbon 1S2 2S 2P2.

Neon, argon, krypton.. inert gases are used in bulbs.

Electric bulb is the only used to [helium, argon, neon] because the nitrogen is giving by a [nitrous oxide].
