What Causes Flickering Lights?


Flickering lights can be an annoying experience, particularly when trying to do something that requires proper lighting. They can also be a sign of a more serious underlying issue. If you've been wondering what causes your lights to flicker, you've come to the right place. In this post, we explore some of the common reasons that can cause flickering lights in your home.


1. Loose Bulbs

One of the most common causes of flickering lights is loose light bulbs. When the bulb isn't securely in position, it can vibrate, and this can make the light flicker. Typically, this can be solved by tightening the bulb. Suppose you've tried that, and the problem persists. In that case, it's best to replace the bulb entirely.

2. Faulty Light Switches

Another common cause of flickering lights is faulty light switches. If the switch that controls your light is defective, it may not be sending a stable flow of electricity to the bulb. This can cause your lights to flicker, and it can also be a safety hazard. If you notice that your lights only flicker when you use a particular switch, it's best to call a professional electrician to fix the problem.

3. Overloaded Circuits

Overloaded circuits can also cause flickering lights. An overloaded electrical circuit occurs when more current flows through a circuit than it can handle, causing the circuit to trip and the lights to flicker. This can be remedied by reducing the number of appliances or devices that are plugged into the circuit. If you're unsure about how to do this, consult a professional electrician.

4. Malfunctioning Electrical Panels

At other times, the problem may be larger than faulty bulbs or switches. Frequently, the flickering lights may be a sign of a more serious electrical issue. For example, if an electrical panel isn't functioning correctly, it can lead to unstable power. If you notice that several lights in your home flicker simultaneously or other electrical appliances behave erratically, it may be time to seek professional help.

5. Voltage Variations

Finally, voltage variations can cause flickering lights. Energy providers supply varied voltages at different times of the day. The lateral fluctuations in voltage can lead to flickering lights as bulbs struggle to maintain their steady light output.



Flickering lights are a typical issue in most homes. In most cases, the lack of proper electrical connection results in the problem. With adequate care, this problem can be resolved. However, if you're not confident in your ability to troubleshoot these problems yourself, it's best to call a professional electrician to handle them.
