Why Are My Lights Flickering?

There are a number of reasons why the lights in your home may be flickering. Some of these reasons are harmless and to be expected, but there are some instances when flickering lights can be a sign of trouble. This is why it’s best to address the issue as soon as you notice it. The following guide will walk you through the common causes of flickering lights.

Lights Flickering due to Loose Light Bulb

One reason you might be experiencing lights flickering is due to a loose bulb. If a bulb sits loose in the light socket, it will not have a consistent power supply – this is the reason for the flickering lights.

But not to worry because this is a fix even the least experienced handy person can handle. Turn off the light and allow the bulb some time to cool. Then tighten the bulb so it sits snug in the socket and turn the light back on.

Some Light Bulbs are Prone to Flickering

Have you found yourself asking, “why are my lights flickering?” Depending on the type of light bulb you’re using, you might have some that are prone to this behaviour. Or perhaps you are using light bulbs that are not meant to be used with light dimmers.

Some fluorescent light bulbs are known to flicker if the room is especially cold, or when you first flip the switch to turn the lights on. If you find this bothersome then you should consider replacing the fluorescent bulb with a different type.

Lights Flickering due to Circuit is Overloaded

If you notice that your lights start flickering when you turn on an appliance – like a microwave, dishwasher, or vacuum – this could be a sign of a circuit that is overloaded. These devices require a large amount of electricity to operate and draw it from the same source as your lights.

If the flickering is minimal, you can probably ignore it, but if you’re seeing the flickering often and lasting for prolonged instances, it might be worth upgrading and installing new circuits in the room.

Lights Flickering due to Change in Voltage

Fluctuating voltage can be another reason for flickering lights. It is normal for slight changes in voltage, but it should always sit between 115 and 125 volts. If you are finding changes in voltage that fall outside this threshold, you should call a certified electrician to diagnose the issue.

Some signs of significant change in voltage include:

  • lights dimming and flickering when large appliances power up
  • flickering persists after appliance is powered off
  • lights dim unexpectedly
  • bulbs are burning out more often than usual
  • electronics and appliances powering off or not working properly

Lights Flickering due to Wiring is Loose

Loose wiring can be an explanation for your flickering lights. Loose wires are always something to address immediately. It can occur for a few reasons such as improper installation, or old and aging wiring.

This is a fire hazard that should be addressed as soon as possible. It’s always recommended to hire a certified electrician to handle your electrical needs.
