Why Are My Lights Flickering? Common Causes and What You Can Do About It

If you live in Suffolk County, Long Island, and you’ve noticed your lights flickering—especially during windstorms or when large appliances kick on—you’re not alone. Here’s a deep dive into why this happens, what it could mean, and when it’s time to call in a licensed electrician.

Top Reasons Your Lights Are Flickering
Loose Light Bulbs or Fixtures
Let’s start with the simplest fix: sometimes the bulb just isn’t screwed in tight. If the connection isn’t solid, you might get a flicker. Try gently tightening the bulb (make sure the light is off first!).
Pro Tip: If you’re using LED bulbs in older dimmer switches, they might not be compatible—leading to that annoying strobe effect.
Overloaded Circuits
Ever notice your lights dim or flicker when the microwave or AC kicks on? This could be a sign that your circuit is maxed out.
Real-Life Example: A homeowner in Ronkonkoma called us because their kitchen lights flickered every time they ran the dishwasher. Turned out the kitchen was wired on the same circuit as the laundry room—definitely not ideal.
Faulty Wiring or Connections
This is where things get serious. Loose or frayed wiring behind outlets, switches, or fixtures can cause intermittent power—creating flickers and fire hazards.
Warning Sign: If flickering is accompanied by a burning smell, buzzing sounds, or hot outlets—shut off the breaker and call an electrician immediately.
Problems with the Electrical Panel
Your panel is the heart of your home’s electrical system. If it’s outdated, damaged, or not equipped to handle your household load, it can cause fluctuations throughout the home.
Tip for Suffolk County Homes: Many houses in Smithtown, Huntington, and Islip were built in the ’70s and ’80s with panels that aren’t suited for modern energy needs. If you haven’t had your panel checked in a while, now’s the time.
Issues with the Utility Company
Sometimes the problem isn’t in your house at all—it’s on the power company’s end. Fluctuations in the grid or a failing transformer in your neighborhood could be the cause.
Quick Check: Ask your neighbors if they’re experiencing the same issue. If yes, it’s likely an external problem.
What Can You Do?
Tighten Bulbs & Check Fixtures: Start with the basics.
Track When It Happens: Does it only happen with certain appliances or at specific times?
Call a Licensed Electrician: Especially if you suspect wiring or panel issues. This isn’t a DIY moment.
