Filament is a thin part of incandescent bulb which is the source of electric light that electric current passes through and heated it until it produce light.
Mains filament
All kinds of incandescent lamp, and all types of light bulb contains filament. But there are several kinds of filament applied each type of light bulb.
In vacuum tube devices, one electrode of the tube (the filament) needs low voltage at relatively high current, while another one (the plate) needs a high voltage at relatively low current. It's hard to build a single power supply to provide both of these, so the filament is usually supplied from its own separate transformer. Nobody has worried about things like this since a short time after transistors came along.
In an incandescent light bulb the wire that gives off the light is called the Filament.
An incandescent bulb has a filament that has a resistance. The value of the resistance determines the current that will flow for a given supply voltage. The heat generated by the current flowing through the filament gives off light. As the resistance of the filament decreases the current increases and you get more light.
Hi beam lights only the High brightness filament of the headlight.Lo beam lights only the Low brightness filament of the headlight.DRL lights only the High brightness filament of the headlight, but at reduced current.Do you see the pattern?
The standard 1157 or similar two filament bulbs contain an upper (small diameter) filament for the parking lights and a lower (larger diameter) filament for the brake and flasher applications. The new LEDS operate from one diode.

light bulbs have metal contacts that connect to an electrical circuit and a filament. power lights up the filament in the bulb .
It can if it is a dual filament bulb as found on most US. makes. The brake light filament can short over to the tail light filament inside the bulb and when the brakes light is activated, all the tail lights and front marker lights will light also, probably blowing fuses.
Yes, they are known as dual-filament bulbs.
For incandescent lights, they operate with a superheated filament. The filament slowly burns away and eventually breaks, opening the electrical circuit.
For Light bulbs:The filament is made of tungsten. There is a inert gas used around the filament which is usually argon, neon, or nitrogen.
They light up because of the filament in the light
If the bulb lights up then electricity is passing through the bulb. If the bulb doesn't light up then electricity is not passing through.
because filaments are generally good conductors of heat , so the filament burns first and then gets heated up and then gives light.
