Flickering Lights in House – Why it happens and How to Fix Them

When your lights flicker, it can be a little nerve-wracking. Some people even wonder if there’s something wrong with their house or if they’re being watched by a demon. The truth is, your flickering lights could be anything from a minor annoyance to a sign that something is very wrong with your wiring or lights.

Flickering lights in the house is one of the most common problems we encounter when it comes to lighting. And while they might seem like a minor annoyance at first, they can have a major impact on the way your space looks and feels. That’s why it’s so important to understand why your lights flicker.  In this post, we’ll explore the reasons why your lights are flickering, how to check to see if your lights are at fault, and how to fix them if they are.


What Is Flickering?

Lights are the ones that are responsible for illuminating your home, office, or other space. And while all lights can occasionally flicker, a flickering fixture doesn’t stay on consistently. When lights flicker, they aren’t always fully lit. They might have one half of the bulb lit, then the other, then the other, and so on. Below are some of the reasons which are explained in detail:

Varying Voltage:

Voltage variation is a common occurrence. While your mom uses mixie, you might have noticed that your house lights start flashing as in a horror movie. It is due to the consumption of high voltage by a large appliance which leaves other devices to flicker. If your light continues to flicker even after you stop using a large appliance, chances are that it was damaged during the previous on-off fluctuation. Consult an electrician immediately and bring it back to normal.

The bulb is burnt out

This is a common problem among homeowners. While it’s easy to ignore it at first, For Family and kids’ safety it’s important to remember that a burnt-out bulb is a big part of the cause behind flickering lights. That’s because a burnt-out bulb generates a lot of heat, which can cause the wiring and fixtures to break down. Call an experienced electrician and know if that’s the case. If so, replace it with a new bulb.


Dangling light bulb

A loosely attached bulb to its socket may flicker. So check and fix it. Also, when it comes to the screw on a light bulb, it’s super important that it’s exposed to high wattage at all times. This is because it allows the bulb to light up properly, without having it overheat. The screw is what keeps the filament in place and allows it to produce light. If you’ve ever taken a screw out of a light bulb and then put it back in, you’ll know that it doesn’t light up right away. This is because the filament wasn’t properly exposed to high wattage. It’s also important to keep in mind that screws aren’t always the same size across different light bulb brands. It’s also worth noting that not all screws are the same size, so you’ll want to double-check with your light bulbs.


Install a dimmer switch.

A dimmer switch is an electronic device that allows you to regulate the amount of light coming from your fixtures. This is especially helpful if you have a lot of windows or doors in your home that is often left open, as it will help you control the amount of light coming in from those areas. A dimmer switch can also come in handy if you’re using recessed lighting, as it gives you the option to turn off the light completely from the switch.


If you’re still seeing flickering, check your wiring.

If your flickering lights don’t get fixed for any of the DIY solutions, there’s a good chance that your wiring is the problem. That’s because wires transfer electricity, and if they’re damaged in any way, they won’t allow your lights to work properly. First, make sure your wires are securely fastened to the surface. This is especially important if you have a lot of windows or doors in your home. Second, make sure the wires are properly aligned. This is especially important if you’re using recessed lights or dimmers. Third, make sure your lights are turned off when they aren’t in use. This is important because it will help protect your wires and make sure they don’t break down.
