What is the resistor inside a light bulb?
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.

What element is essential in a light bulb?
In the old style filament lightbulbs it was tungsten (wolfram).
Where is there a resister in a light bulb circuit?
In an old-fashioned light bulb, the part that emits light is a resistance. When current flows through it, it heats up so much that it glows - it emits light.Due to their lousy efficiency, these light bulbs should be discarded, in favor of fluorescent light bulbs or LED light bulbs.In an old-fashioned light bulb, the part that emits light is a resistance.

How does the light bulb help?
If you are asking for operation for old light bulbs. Then there is a tungsten filament is provided in the bulb which get heated on supplying power and emmits light and heat.

How do you change the tail light on 2003 Suzuki SX?
You might have to go in through the trunk of the car to take the light cover and all of that out go to the store ask for a tail light for your model when you get the light DO NOT TOUCH THE BULB!!! This means you have a faulty bulb that you paid for if you touch it. The light bulb reacts with the heat from your fingers and goes faulty. Grab it by the aluminum or the metal at the bottom of the bulb and carefully slide it in back like your old bulb that you replaced try and copy what you saw with the old bulb.
