What causes flickering lights in my home and how to fix them?

Flickering lights in a home are usually caused by a loose bulb or connection, a failing switch or dimmer, an overloaded circuit, or voltage fluctuations from the utility. The most common cause is a loose bulb or lamp socket that breaks contact as the fixture warms or vibrates. As electricians, we also see dimmers that don’t match LED bulbs and circuits that dip when big appliances start. Our team handles these issues daily across North Orlando and nearby Oviedo homes.

Check these common fixes and decision signals:

• Loose bulb or bad lamp socket: gently tighten or replace the bulb or lamp.
• Incompatible or failing dimmer/switch: use an LED‑rated dimmer or replace the switch.
• Overloaded circuit or shared neutral: flicker when appliances start means the circuit needs evaluation.
• Utility or main connection issue: whole‑home flicker, panel buzz, or heat needs urgent service.

If you see widespread flicker, heat, or a burning odor, turn off power at the breaker and call a licensed electrician.
