Flickering lights are either an annoyance or a cause for concern. Often, all it takes to resolve the issue is a light bulb or switch adjustment. However, there are times when you’ll need an electrician to diagnose the problem to minimize the risk of fire. To help you stay safe, here are some common reasons why lights flicker and how you can tell when it’s time to contact a professional.

What Are the Possible Causes of Flickering?

In most cases, a fluctuation or drop in voltage leads to flickering lights. Wires have some degree of resistance, and a fraction of the voltage is used to help the electric current overcome that. When there isn’t enough power, the lights don’t stay on. LED and fluorescent lights are more likely to flicker due to a failing ballast or an improper connection to a dimmer.

It can also be caused by a loose bulb or faulty light switch. For these issues, tighten your bulb or replace your switch. If that doesn’t fix the problem, leave the diagnosis and repair to an electrician.

When Do I Call an Electrician?

Major electrical problems that cause flickering lights are a fire hazard. These may include loose wiring, which could lead to electrical fires. If you notice a significant change in your utility bills or an increase in the frequency of flickering, call an electrician. Burning smells, cracking or sizzling sounds, and blown fuses are also hazards. A professional will determine whether the issue is caused by an inadequate voltage supply in your home and update your system to prevent future fluctuations.
