because filaments are generally good conductors of heat , so the filament burns first and then gets heated up and then gives light.

Can electricity still pass through a bulb which has fused?
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.
How does a light bulb light?
light bulbs have metal contacts that connect to an electrical circuit and a filament. power lights up the filament in the bulb .

Can a bad bulb cause all brake lights in a 98 ford ranger to fail?
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.
Why does one headlight go out when the bright lights are turned on?

What is the difference between a 1156 bulb and 7506 bulb?
The 1156 bulb has one filament in it, which means it only lights on or off. The 7506 on the other hand, has two filaments. The first filament is usually lit up when the headlights or auxiliary lights turn on, and alike the 1156 bulbs (they are usually used for taillights) they light up when they get the second side with voltage sent through them. Hope this helps!
Why does the brake light not light up on 1997 Quest when you turn on the light but it light when you brake?
Brake lights only come on when you press the pedal. The brake light is either a different bulb or filament in a dual-filament bulb than the tail light.

In an incandescent light bulb this is the filament. It is usually made of tungsten.
Are the bright lights and the dimmer lights on a 2004 Toyota Highlander in the same bulb?
Yes, they are known as dual-filament bulbs.
Why can't a bulb turn on without electricity?
An incadescent bulb lights up because the voltage source creates a current through the filament of the bulb and it heats up because of its composition and gives off light as a result. No electricity, no voltage and no current.
How a lamp lights with the use of electricity?
a light bulb as the ones used in lamps. lights by fine filament inside the sealed vacuum bulb. one side of the filament connects to the bottom raised portion. the other end of filament connects to the silver screw in part. when the light bulb is screwed all the way down, the bottom of the bulb hits the slightly raised flap at the bottom of the socket. pos.+. and the side of socket is in contact with the side of bulb. Neg.-.put on switch and and electricity flows through the filament, you have light.
