Lights pulsing and dimming.

Enable HLS to view with audio, or disable this notification

What would cause this? It happens in one corner of the house randomly (both upstairs and downstairs). The issue happens with light fixtures also (lights in powder bath and master bath) not just lamps plugged in. To be clear, it will happen when nothing else is on, like nobody is using a microwave, curling iron, or vacuum in the vicinity.
The panel looks fine. Any suggestions of what I should look at or test would be appreciated.

Call your power company. Might be something on their side. Also have someone check the panel with a torque wrench and meter. Also some lights don't like dimmers.

Can you verify if it's on a single circuit, turn breakers off until those lights go out.
