Why Are My Lights Flickering and What Should I Do?

Flickering lights can be more than just a minor annoyance—they’re often a signal that something in your electrical system needs attention. While an occasional flicker might not raise concern, frequent or unexplained flickering is worth investigating. Addressing the issue early can help prevent safety hazards and costly repairs.

Common Causes of Flickering Lights

Loose Light Bulbs or Fixtures

One of the most common—and easily fixable—causes is a loose bulb. If your light flickers when bumped or moved, try turning off the power and tightening the bulb. It’s also a good idea to check that the fixture itself is secure. In many cases, this simple step solves the problem.

Circuit Overload

If lights dim or flicker when large appliances turn on—like the microwave, washing machine, or air conditioner—it may be due to a temporary voltage drop. This happens when the demand on a circuit exceeds what it can handle. Older electrical panels are especially prone to this issue.

Faulty Switches or Dimmers

A flickering light could be traced back to a faulty switch or dimmer. Incompatible bulbs, especially LED lights paired with older dimmers, can cause visible flickering. If the issue only happens with one particular light or switch, that’s a good place to start troubleshooting.

Wiring Issues

Loose, frayed, or outdated wiring can lead to unpredictable flickering and should never be ignored. If lights in multiple areas flicker at random times, wiring may be the root cause. This is a serious issue that can create fire risks if left unresolved.

Outdated Electrical Panel

Your home’s electrical panel is the hub that manages how power flows to different rooms. Panels that haven’t been updated in decades may struggle to handle modern energy use. If you’re experiencing regular flickering across your home, your panel could be overloaded or deteriorating.

When to Call a Professional

If tightening bulbs and replacing switches doesn’t stop the flickering, it’s time to bring in a licensed electrician. Persistent or widespread flickering may indicate deeper issues that aren’t safe to ignore. A professional inspection will pinpoint the cause and ensure your home’s electrical system is operating safely.

Call an electrician if:

• Lights flicker throughout your home

• You notice a burning smell or warm outlets

• Circuit breakers trip frequently

• Flickering is accompanied by buzzing or crackling sounds
