Why Are My Lights Flickering?

In this brief article brought to you by Mr. Electric, we explore some potential reasons why your lights are flickering. If you’d rather have a certified electrician come in and investigate, then call Mr. Electric. We’re here to schedule an appointment or arrange emergency electrical repair service for as soon as possible.

Loose Bulbs

The most straightforward cause of flickering lights is a loose bulb. When a bulb isn’t securely screwed into the socket, it can cause intermittent contact which often leads to flickering. Ensure that all bulbs are properly tightened but be careful not to overtighten as this can damage the bulb or socket.

Faulty Light Switches

Light switches can wear out over time, especially if they are frequently used. A worn or defective switch may not maintain a solid connection, causing the light to flicker. Replacing old or malfunctioning switches can often resolve this issue.

Loose Wiring

Loose or frayed wiring is a more serious cause of flickering lights and poses a significant fire hazard as well. Loose connections at the fixture, in the electrical panel, or along the circuit can cause lights to flicker. If you suspect loose wiring, you should contact a licensed electrician to inspect and repair the issue promptly.

Overloaded Circuits

An overloaded circuit happens when too many appliances or devices are drawing power from the same circuit. This can cause the voltage to fluctuate, leading to flickering lights. Redistributing the electrical load or upgrading the electrical system to handle more power can fix this problem.

Voltage Fluctuations

Voltage fluctuations, or power surges, can cause lights to flicker. These fluctuations can be due to large appliances cycling on and off, faulty wiring, or issues with the utility service. Using surge protectors and having an affordable electrician check for wiring issues can help manage voltage fluctuations.

Incompatible Dimmer Switches

If you’ve recently installed LED bulbs and they flicker when used with a dimmer switch, the issue may be compatibility. Not all dimmer switches are designed to work with LED lights. Upgrading to a dimmer switch specifically designed for LEDs can eliminate flickering.
