A Portland Homeowner’s Guide to Flickering Lights

Flickering lights may seem minor, but they can signal loose wiring, overloaded circuits, voltage fluctuations, or electrical panel issues.

Common Causes of Flickering Lights

• Loose light bulbs or fixture connections
• Overloaded circuits
• Loose wiring connections
• Voltage fluctuations
• Outdated or failing electrical panels

While some flickering issues are simple, others may indicate a deeper electrical concern.

When Should You Be Concerned?

Call a licensed electrician if:

• Lights flicker throughout the entire home
