This could be because so many of the light bulbs are now so cheaply made they can't hold up to regular use. If this is a regular occurrence then you may have an electrical supply problem. In the United States the power coming into your home varies over time, but should be close to 120 volts. If it is too high or you are getting power spikes the only thing you may notice is burned-out light bulbs, but you may actually be shortening the life of some of your most expensive household appliances. Refrigerator and Air Conditioning compressors may burn out prematurely if the voltage is too high. Voltage fluctuations can also be caused by an improper ground on the circuit or coming into your house. Usually your power utility company will check your system out at no charge. Sometimes there may be a problem with the transformer on the line into your house. If there are no other problems, try using heavy duty light bulbs rated for 130 volts instead of the regular 115/120 volts. They have a heavier element that can take rough handling and power fluctuations better. You may have to get them at an electrical supply house. This is common problem in older homes. Keep in mind that the current in a circuit is the same throughout the circuit. Therefore if there is resistance in the wiring, that resistance increases the current through the bulb. <-- this is wrong The first answer above makes sense, the last sentence of the second answer does not. Reason is that the statement "Therefore if there is resistance in the wiring, that resistance increases the current through the bulb" is totally wrong. For any given mains supply voltage, any extra resistance put into a circuit will decrease the current in that circuit, which of course includes the bulb. If there is an extra-long wiring distance then you should use cable that is thicker than normal. That will keep the circuit resistance as low as possible. If you use too thin a cable for a long circuit run its resistance will be higher than it would be if a thicker cable were used. The thinner cable will "steal" more voltage from the light bulb (or whatever other device the cable is supplying) than a thicker cable will. This has at least 2 bad results: too thin a cable will get much hotter than it should (a possible fire risk) and the lamp will not burn brightly enough. In that case you might be tempted to try an even stronger wattage lamp, which will draw even more current through the thin cable, increasing the voltage dropped in the cable even more... (An even worse fire risk!) Another idea is: Use more Compact Fluorescent Lamps! See the related question: "What savings can a compact fluorescent lamp give?"

What happens to the light bulbs when one is disconnected?
It depends on the light bulbs. Some will all go out once one is disconnected and only that one that got disconnected will go out.
What would happen if one of a set of light bulbs burn out in a parallel circuit?
It depends on the circuit. If it is a constant-current circuit, any light bulbs connected in parallel with it will become brighter. If it is a constant-voltage circuit like a typical household circuit, nothing will happen. Any connected in series with it will go out.
Can light bulbs contain more than one filament?
Yes, automotive bulbs have more than one for turn and tail lights. 3 way bulbs in house lamps have 3.
How many light bulbs are used in the UK each year?
alot... there is over 17 terawatts used in one year and one terawatt can light up 3 billion light bulbs so im guessing like 3-6 billion light bulbs a yearprobably more though

What are man made luminous objects?
Light bulbs would be one.
Where can one get Full Spectrum light bulbs?
There are many places where one can get full spectrum light bulbs. Some of these would include home improvement stores such as the Home Depot, or straight from a manufacturer such as Verilux.
How would you identify a defective light bulb if 15 bulbs are connected in parallel?
it will be the one that is dark
Where can one purchase car light bulbs?
One can purchase car light bulbs from the following sources: Demon Tweaks, eBay, LED Choice, Power Bulbs, Halfords, Power Bulbs, Auto Zone, Auto Bulbs Direct.
How many years would it take to recoup the entire cost of low energy light bulbs?
A few months. You'll have to do the calculations by yourself, for your case - both the cost of light bulbs and the cost of electricity may vary depending on the region. Assume that the low-energy light bulbs use about half, or one third, of the old-style incandescente light bulbs.
Where can one purchase Sylvania light bulbs?
You can purchase Sylvania light bulbs online from stores such as The Home Depot. Alternatively, you can also purchase Sylvania light bulbs from retailers such as Amazon.
Why do all bulbs on right rear not light up but do light up if switched to left side?
burnt bulbs replace them correct answer if the bulbs work on one side, but same bulbs dont work on other side , u have a broken wire to the side that doesnot work if the bulbs were burnt out, they would not work on either side
What happens to the light bulbs when one is disconnected?
It depends on the light bulbs. Some will all go out once one is disconnected and only that one that got disconnected will go out.
Why would brake light fuse keep blowing after stepping on the brakes a few times on a 1991 corvette?
It is possible that one of the bulbs is shorting out. Try replacing the brake light bulbs, if that doesn't work, troubleshoot the brake light switch.
How are light bulbs different from natural light?
No one needs to be smart as this!
Why would one brake light and one reverse light not work on a 2002 dodge ram 1500?
most likely ground wire problem Bad bulbs?
Why is the light bulb so important?
Without the light bulb, we would have to use the sun candles and when the sun is not here, we would have to use candles. Light Bulbs are one of our things that we need to live.
