Do you have lights that flicker? If you do, you know how annoying this can be. Here are some common reasons why this happens.

Before you begin any work, be safe with electric components and wiring. Switch off power at your circuit breaker panel and test your work area for energized wires using a voltage tester. If you are not comfortable working around electric components, hire a licensed electrician.

Common causes of light flickering:

Wall switch failure

If your wall switch feels spongy and does not quickly snap on and off, this can cause light flicker. 

Solution: Replace the switch.

LED lights

Many LED bulbs are not compatible with older dimmer switches. Flickering can also come from the bulb itself as it might not be compatible with a dimmer. 

Solution: Upgrade your dimmer switch and/or try a bulb that is compatible with dimmers.

The socket is corroded 

You can identify this is the cause if you tap the area around the bulb causing it to flicker.

Solution: Replace the socket.

Voltage fluctuations 

Some LED bulbs might flicker when a device such as a HVAC unit or any other motor-driven load turns on and off. While this can be due to the sensitivity of the bulb itself, it could also be a symptom of a larger issue with your electrical system.

Solution: To determine if the flicker is a symptom of a larger issue, consult a licensed electrician to review your home’s electric system.
