Key Causes of Flickering Lights 

So, what is causing those lights to flicker, anyway? Here are the common culprits.

Loose or Faulty Bulbs

Sometimes, the problem is as simple as a loose or faulty bulb. If a bulb isn’t screwed in properly, it can cause an intermittent connection, leading to flickering. Make sure to turn off the light and let the bulb cool before checking it. Tighten it gently but firmly. If the flickering continues, replace the bulb with a new bulb to see if that resolves the issue.

Electrical Wiring Issues

Flickering lights can also be a sign of electrical wiring problems. Over time, wires can become loose or frayed, causing intermittent connections. This is a more serious issue, as faulty wiring can lead to electrical fires. If you suspect wiring problems, it’s crucial to call an electrician immediately to inspect and repair the wiring.

Overloaded Circuits

An overloaded circuit is another common cause of flickering lights. When too many devices are plugged into a single circuit, it can cause the lights to flicker as the electrical load fluctuates. Try unplugging some devices to see if the flickering stops. If it does, you might need to redistribute your devices across different circuits or upgrade your electrical system to handle a higher load.

Faulty Light Switches

Sometimes, the problem lies with the light switch itself. A faulty switch can cause flickering due to a poor connection. You can test this by gently jiggling the switch to see if the flickering stops or gets worse. If the switch is the culprit, it’s best to have it replaced by a professional to ensure safety and proper function.
