Why Your Lights Keep Flickering (And How To Fix It Safely)
Flickering lights aren’t just annoying — they can signal dangerous electrical problems.
Sometimes the fix is simple.
Other times, it’s a warning sign you shouldn’t ignore.
This guide helps you tell the difference.
Common Causes of Flickering Lights
1. Loose Light Bulb
First thing to check:
- Turn the bulb off
- Tighten it gently
- Turn power back on
This fixes more issues than you’d expect.
2. Loose Wiring
Loose wiring in fixtures or junction boxes causes unstable power flow.
Signs:
- Lights flicker when you touch the switch
- Flickering gets worse over time
This should be inspected by an electrician.
3. Voltage Fluctuations
If lights dim when appliances turn on:
- Your electrical panel may be overloaded
- Your home might not have enough capacity
4. Failing Electrical Panel Components
Older panels can struggle with modern loads.
Flickering across multiple rooms often points to panel problems.
When Flickering Is Dangerous
Call an electrician immediately if:
- You smell burning
- Breakers trip often
- Lights flicker across several rooms
- Outlets feel warm
