That is the filament. Electricity traveling through the filament heats it to the point of glowing brightly - that is the light bulbs "light".
With Thomas Alva Edison's invention of the light bulb, the elements were constructed of Carbon. Newer light bulbs are constructed of Tungsten, which takes much longer to bend into a coil within a coil within a coil, but shines much brighter and lasts for thousands of hours.
light bulbs
It is made of tungsten, a metal with a very high melting point.
Headlight bulbs, high and low beam, parking light bulbs, signal light bulbs, brake light bulbs, dash light bulbs, interior light bulbs, plate light bulbs, etc.
If you mean the brake light, you just have to change the bulb or bulbs.
He conducted electricity wirelessly using the Tesla Coil.
In some light bulbs.
why light bulbs are fragile
Light bulbs emit light.
The electricity runs through a coil of Tungsten. Tungsten has a very high resistance. As per Joule's Law, energy radiated is directly proportional to resistance. The energy radiated is so large that the coil starts to glow and light is produced.

Domestic light bulbs are simply the light bulbs (usually of the filament type) used in the home.
