Master electrician Heath Eastman goes over some reasons as to why your lights might be flickering. Flickering lights are a problem most households deal with at some point, so Heath goes over a few common reasons why a light might be flickering and walks you through some basic troubleshooting.

Skill Level: Beginner

Loose Bulb
• To Fix: Thread the bulb tighter.

Bad Socket
• Light bulb sockets can corrode overtime, especially in outdoor fixtures.
• To Fix: With the switch powered off, check and see if the socket is in good condition. If not, it will probably need to be replaced.

Failing Switch
• The metal connections on the light switch may wear overtime, or the one installed might be a defect and never had a properly made connection at all.
• To Fix: Replace the light switch and see if it works. You can swap the switch with one from another room that you know is working to see if it works in the room that’s flickering.

LED Lights
• Some of the newer LED bulbs simply aren’t compatible with older switches, particularly dimmers.
• To Fix: Try to figure out if the current dimmer switch is “LED compatible”. If not, replace it with one that is. Also see if the LED light is a dimmable bulb.

Where to find it?
Heath demonstrated a variety of light switches and fixtures, which can be found at any home center. In general, he recommends checking the switches to ensure they’re up•to•date and operating properly to troubleshoot any issues with flickering lights.
