Poster could be in the UK or Europe and then will need 20 car batteries.

You can power any low wattage 120V appliance with a inverter, you do not need to replace the filament. You can make a inverter by using a large 120V to 12V transformer, and feeding the 'secondary' coil with 12Vac to run the transformer in reverse and boost the voltage up to 120V.

1. Directly no.

2. If you want battery powered light and a normal sized bulb you will have to dismantle the bulb and replace the filament with LEDs.

3. You could use the LEDs anyway

You are better off using a LED light instead.
Not only can you use lower voltages but you need a lot lees energy to get the same amount of light - which is what you want on batteries.
A normal lightbulb give light ok, but mostly it produces heat.

With a 12V to 120V inverter.

Before we had the fancy LED lamps all flashlights used incandescent light bulbs, same on push bike.

The bulb design voltage must NEVER Ever be less then the battery voltage !

Then wire the bulb across the battery without regards to polarity :-)
