I assume you mean in a miniature light Christmas tree light set.
Assume a 60 bulb set designed for 120 volts.
Each bulb has 120/60 or 2 volts across it when all bulbs are lit.
But each bulb has a tiny insulated wire across the contacts inside the bulb. The insulation can handle small voltages, but not 120 volts, so when the filament breaks, the voltage on the dead bulb goes from 2 volts to 120, breaking the insulation and welding the wire across the leads.
This newly welded wire then completes the circuit and the other bulbs instantly relight, now with 120/59 or 2.03 volts across each bulb, so they get slightly brighter.

Why does your dimmer switch burn out when one of your bulbs blow?
Dimmers are rated to handle upto x amount of watts (x can vary) When one of your bulbs blows if the amount of watts used by the bulb during its blowout exceeds the amount of watts your dimmer is rated for it is possible the dimmer burns out. While this may be theoretically true, when the dimmer is rated for 600 watts and a 50-watt bulb blows and so, the dimmer, this doesn't explain why. No bulb blows out at, say 500 watts. Any other answers? Feel free to wipe out mine and the one above if you know the real answer.
Can i build a electric circuit by using wire a bulb a battery?
yes! connect all the bulbs in parallel.. i.e. battery positive terminal will be tied to one side terminals of bulb and other terminal to the other. but it will result in less power delivered.. and fast battery usage..
What elements comprises a light bulb?
It depends on the type of bulb. Tungsten is the most common element in light bulbs. But there are neon based bulbs also
How does the amount of magents and wire affect the brightness of a light bulb?
The brightness of a light bulb directly has no direct relationship with magnets and wire. The bulbs brightness is determined by the wattage of the bulb. The higher the wattage of the bulb the brighter the bulbs light output.
Does a daffodil comes from a bulb?
Daffodils grow from bulbs
Why in houses if one bulb is fused the rest of the bulbs continue to glow?
If a circuit is wired in parallel, all the bulbs have their own independent access to electricity, so if one bulb goes out, the others are not affected. If the circuit is wired in series, then one bulb going out will block the current to all the other bulbs as well.
Why do both headlights not work on your vauxhall corsa?
Because both the bulbs are blown? Most drivers only drive around in towns, which have street lighting. As a result, when one bulb blows it is not noticed by the driver. Only when the second bulb blows does it become noticeable. Plus, personal experience shows that some drivers check the wrong bulb, as from 2001 Corsa's have 3 bulbs in each headlamp.
Is the halogen bulb a hotter heat then other light bulbs?
sometimes.It depends on the other bulbs
How do you find out why your turnsignal and brakelights won't work on a 1999 f-150 and it is not the fuse?
check your bulbs. if a bulb blows they won't work.
When you remove a bulb from a three bulb circuit and the other two bulbs go off then the bulbs must have been connected in?
help :(
In which circuit did screwing out one bulb not influence the lighting of the other bulb?
A parallel circuit will not effect the other bulb. If the bulbs are in a series circuit the other bulb will not turn on.
Would you use Series or parallel circuit for Christmas lights?
Yes you would use a serial circuit You would use parallel circuit lights for a Christmas tree because if you used series circuit lights, and one of the bulb blows, the rest of the bulbs will go out. But with parallel circuit lights, if one bulb blows the rest of the bulbs will remain their brightness.

Why does it not effect any of the light bulbs when you take one light bulb out from the parallel circuit?
EASY.The removed light bulb does not have any connection to the other light bulbs. While it's socket that was holding the lght bulb has power running through it to the other bulbs also.
What happens when you remove one bulb from a socket in the parallel?
That bulb goes out. The other bulbs remain on.
What is the plural form of the word bulb?
The plural form of the word "bulb" is "bulbs."
What happens to the bulbs in parallel circuit if one of the bulbs buns out?
The other bulb remain to glow with same intensity.
