the wire in your light bulb is a resistor :)
the inside of a light bulb is called the filament
In an 'old fashioned' incandescent light bulb, the only electrical part inside is the filament wire itself. When you put a meter across a cold bulb and measure the resistance, you're measuring the resistance of the filament. More modern and more efficient artificial light sources, like fluorescent tubes, LED lights and CFLs, have additional electronic components inside the structure of the bulb.

The globe is the outer glass shell. The shaped coil inside is the filament. Wires and the stem support the filament inside the bulb. There are gases within the light bulb to prevent it from burning out. And the base is to securely support the bulb.
Among others, the filament of an incandescent light bulb is a resistor- which gives off heat and light.
It is the filament.
The kind of gas that is in a light bulb is called Argon.

A resistor slows the flow of electricity, and converts the electrical energy into heat. You don't WANT heat - you want LIGHT, so we generally do not put resistors in lighting circuits. If there is a resistor in the circuit, it will cause some of the energy that would normally be converted to light to be converted into heat instead, so the light bulb will glow less brightly. A variable resistor in such a circuit is sometimes called a "dimmer".

Electricity creates heat when flowing through a resistor such as the filament in a tungsten light bulb, and, since the heat can not be readily conducted away in the near vacuum inside a light bulb, the heat eventually raises the temperature of the filament to a value that leads to radiation of light from the hot filament.

Yes, the inside of a light bulb is a partial vacuum.
