Why Are My Lights Flickering? Causes & How To Fix

You’re reading a book, cooking dinner, or relaxing in front of the TV when suddenly—your lights start to flicker. It might last only a second, but if it happens often, it can be frustrating and even concerning. If you’ve ever asked yourself, “Why are my lights flickering in my house?,” you’re not alone. Flickering lights are one of the most common electrical issues homeowners face. While sometimes it’s just a loose bulb, other times, it may signal a more serious wiring or circuit issue. So, why are my lights flickering? This guide from Lywood breaks it down and shows you how to fix flickering lights in your house safely.

Understanding Why Lights Flicker

Lights can flicker for many reasons, and not all are dangerous. Some issues, like a loose bulb or faulty fixture, are quick fixes. But if you notice multiple lights flickering in your house or lights dimming when you use appliances, it’s often a sign of something deeper going on in your electrical system.

Common Causes of Flickering Lights

1. Loose or Faulty Light Bulb

Sometimes, the answer is simple: a bulb that isn’t screwed in tightly or has gone bad. This creates an inconsistent connection, causing your lights to flicker.

How to fix it: turn off the power, check the bulb, and make sure it’s secure. If the problem continues, replace the bulb.

2. Faulty Light Switch or Fixture

Worn-out switches and fixtures can interrupt the electrical connection. This can cause lights to dim, buzz, or flicker when you flip the switch.

How to fix it: replace the switch or fixture. If you’re unsure how, contact a licensed electrician for help.

3. Overloaded Circuit

If your lights flicker when you use high-powered appliances—like a vacuum, microwave, or air conditioner—it could mean the circuit is overloaded. The electrical system can’t keep up with the demand, causing lights to dim or flicker. Get in touch with Lywood to have our team take a look!

4. Loose Wiring or Connections

Loose wires are one of the most dangerous causes of flickering lights. They can create arcing, which is a serious fire hazard. If flickering happens throughout your house, loose wiring in the electrical panel or system could be to blame.

Warning: do not attempt DIY fixes—this is a job for a professional electrician.

What to Do When Multiple Lights Flicker in Your House

If one bulb flickers, it’s probably a quick fix. But if you notice multiple lights flickering in your house or lights dimming when you plug something in, it’s time to take action.
  • Check and tighten bulbs.
  • Replace faulty switches or fixtures.
  • Reduce strain on overloaded circuits.
  • If flickering persists, call a licensed electrician.
