Why Are My Lights Flickering? Common Causes & How to Fix Them

What Causes Flickering Lights?

There are several possible reasons why your lights are flickering. Some are simple and easy to fix, while others require professional electrical repair. Below are the most common causes:

1. Loose Bulbs or Fixtures

Sometimes, the fix is as simple as tightening a loose light bulb. If a bulb isn’t screwed in properly, it can cause intermittent flickering. Similarly, faulty connections inside a light fixture can create the same effect.

What to do:

• Turn off the light.
• Carefully unscrew the bulb and reinsert it securely.
• Try replacing it with a new bulb to see if the issue continues.

If the flickering persists, the problem is likely elsewhere in your electrical system.

2. Overloaded Circuits

When multiple appliances are running on the same circuit, it can cause power fluctuations, leading to flickering lights. This is especially common when large appliances, such as refrigerators or air conditioners, start up.

Signs of an overloaded circuit:

• Lights dim when a major appliance turns on.
• Multiple lights flicker at the same time.
• Circuit breakers trip frequently.

What to do:
If an overloaded circuit is the issue, Premier Electric & Design Inc. can assess your home’s electrical load and recommend solutions, such as installing dedicated circuits for high-power appliances.

3. Loose or Faulty Wiring

Loose or deteriorating wiring is one of the most dangerous causes of flickering lights. It can lead to electrical fires if left unchecked.

Signs of loose wiring:

• Flickering gets worse over time.
• You smell burning or see sparks near outlets or switches.
• Your circuit breakers trip randomly.

What to do:
If you suspect loose wiring, turn off the power to the affected area and call a licensed electrician immediately. Premier Electric & Design Inc. specializes in diagnosing and repairing faulty wiring to keep your home safe.

4. Faulty Light Switches or Dimmers

Sometimes, the problem isn’t with the wiring or circuits but with the switches themselves. Older or worn-out light switches can cause flickering, and some dimmer switches are incompatible with LED bulbs, leading to inconsistent lighting.

What to do:

• Try switching the light on and off multiple times—if it flickers, the switch may need to be replaced.
• If using a dimmer switch, ensure it’s designed for the type of bulb you’re using.

If a faulty switch is the cause, replacing it should solve the issue. Premier Electric & Design Inc. can install high-quality, reliable switches for a lasting fix.

5. Utility Service Issues

Sometimes, flickering lights have nothing to do with your home’s wiring. Power grid fluctuations, particularly during storms or peak usage hours, can cause temporary flickering.

What to do:

• Check with your neighbors—if they’re experiencing similar issues, the problem may be with your utility provider.
• If flickering happens consistently in your home but not others, Premier Electric & Design Inc. can inspect your electrical system for underlying problems.

When Should You Be Concerned?

While occasional flickering isn’t always an emergency, certain warning signs indicate a serious electrical hazard:

✅ Flickering happens even when appliances are off
✅ Lights dim significantly when using other electronics
✅ You smell burning or notice sparks near outlets
✅ Your circuit breakers trip frequently

If you experience any of these warning signs, don’t wait—call Premier Electric & Design Inc. for an inspection.

Can Flickering Lights Lead to an Electrical Fire?

Yes. Flickering lights caused by loose wiring, overloaded circuits, or damaged connections can increase the risk of an electrical fire. Even a minor electrical issue can escalate quickly if not addressed.

Warning signs that require immediate attention:

🚨 Lights flicker unpredictably across multiple rooms
🚨 A burning smell near outlets or switches
🚨 Blackened or discolored outlets
🚨 Frequent power surges or breaker trips
