Common Causes Of Flickering Lights
Lights can flicker in your home for any number of reasons. Some of these are harmless and can be easily fixed, while others could indicate serious electrical problems. Let’s take a look at some of the more common causes of flickering lights so that you can get to the bottom of the issue when it comes up in your home.
A Loose Light Bulb
If you have only one flickering light, the problem is likely a loose light bulb. Turn off the light, wait for the bulb to cool, and screw it in tightly. If that doesn’t solve the problem, the flicker is likely being caused by something else.
Using the Wrong Light Bulb
Light bulbs aren’t universal. A bulb that works just fine in one lamp or lighting fixture might not be compatible with something else. Using the wrong bulb could cause a light to flicker if it works at all.
When you replace a light bulb, make sure it’s the proper size and wattage for the lamp or fixture. Also, LED light bulbs are much less likely to flicker than other bulbs, so consider using them when you can.
A Loose Electrical Plug
Some lighting issues have nothing to do with a loose or incorrect bulb. Sometimes, the problem is as simple as a loose electrical plug. If a lamp isn’t working as well as it should, check to see that it’s plugged in properly. Plugging it back in tightly is sometimes enough to fix the problem.
An Overloaded Circuit
Overloaded circuits are usually associated with tripped circuit breakers and appliances that use too much energy, but they can cause lights to flicker as well. If this is happening to more than one light in your home, pay attention to when it happens. It might happen when you turn on a certain appliance or when you’re running too many devices at once. You can try being strategic about what is plugged in and where to avoid the problem, but you should still call an electrician to take a closer look at the problem if it persists.
Outdated Wiring
You might notice lighting and electrical issues if you live in an older home with outdated wiring. Old wiring is potentially dangerous and should be replaced if possible. Once again, schedule an inspection or an upgrade with an electrician before things get any worse.
Arcing
Arcing is when electricity is jumping from two contact points that are close but not connected. Like outdated wiring, it is potentially dangerous and often makes a crackling sound or emits a burning smell. Contact an electrician if you think this is the case. If left unchecked, arcing could damage your appliances or even start an electrical fire.
FAQ: What Causes Lights to Flicker Randomly In a Home?
Why are my lights flickering in only one room or fixture?
If only one light is flickering, the issue is often a loose or incompatible light bulb. Try tightening the bulb or replacing it with the correct size and wattage.
Can the wrong type of light bulb cause flickering?
Yes. Using the wrong bulb for a fixture can lead to flickering or inconsistent performance. LED bulbs are typically more reliable and less prone to flickering.
