One of the common signs you’re dealing with an electrical connection issue is when you start experiencing flickering lights.
It could be caused by a faulty light bulb or light socket. If its multiple lights flickering it could be a faulty switch, dimmer or circuit breaker, or even wiring issues. And sometimes it’s a utility event or weather event.
You can try changing the flickering lightbulb, contacting your utility company or schedule an electrician visit.
