Why do the lights in my house flicker or blink?

Repeated flickering lights can be a sign of a home safety issue.

An occasional light flicker in your home is normal, but if you’ve noticed flickering that didn’t occur before, and is happening regularly, you need to check into it thoroughly and contact an electrician. The constant light flickering can eventually signal problems in the wiring or light fixtures in your home and depending on the cause of the problem, it could lead to serious safety issues.

It can also be caused by a connection failure at the main panel, outdoor meter socket or even at the utility point of service.

All lights actually flicker to some extent. This can be annoying and can be a distraction. The blinking of lights is based on the amount of power that is coming into the lines in your home, it is caused when the power provided to a light source changes or when the power line voltage itself fluctuates.

The usual flickering that we can find in our homes can include problems with bulbs; either if they’re not tight enough or it’s not the right type of bulb. For example, fluorescent lights have a tendency to flicker occasionally, and it shouldn’t be a worry. On the other hand, LED bulbs are the most common cause of flickering due to its dimmer switches. These dimmers sometimes do not do well with lower-voltage LEDs.

Other light flickering can occur with only one lamp. This happens when there are loose light plugs which means that there is a loose connection between the plug and the outlet. Try unplugging and plugging it back in because most of the time it is loose and not properly connected.

Many problems with light switches are usually drawn to some issue that is interrupting the flow of electricity from the wall switch to the light fixture. If your light is already flickering try adjusting the switch on or off and see if it fixes the problem. In other occasions, your lights are blinking or dim when your AC or washing machine is running. This problem may occur due to an overloaded circuit, which means that these appliances are pulling more electrical current than the circuit can handle.

If the flickering happens consistently and becomes a severe issue, there is a problem. Whether you’re concerned about serious issues, or just annoyed by these random flickers, call an electrician ASAP because these are high capacity wires and could result in a fire hazard.

It is important to make sure that the LED or compact fluorescent lamps you buy are dimmable, and the dimmers you choose are compatible with your lamp types. This information is always listed on the packaging and usually on the lamps or dimmers themselves.

This is a complicated and serious safety issue. If you have any concerns, please don’t hesitate to contact us. We will be glad to help.
