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.
Incandescent light bulbs and halogen light bulbs are examples of light bulbs that produce heat.
why light bulbs are fragile
In some light bulbs.
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.
Light bulbs emit light.
Toasters and light bulbs are both electrical appliances that convert electrical energy into heat or light. They both use a filament or coil that heats up when electricity passes through it, though the purpose and outcome of the heat produced is different for each appliance.
