Why Do Your Lights Flicker?

Light flickering can be a frustrating and sometimes even frightening experience. Have you ever been in the middle of cooking dinner or watching a movie and suddenly your lights start to flicker? While it might not seem like a big deal, it could be a sign of a more serious problem. In this blog, we’ll go over 6 common reasons why lights flicker and what you can do about it. Whether you’re an experienced DIYer or you’re looking for a professional electrician in North Vancouver, this guide has you covered.

6 Reasons Why Your Lights Flicker?

Your lights may flicker for the following reasons:

Reason # 1. Loose light bulbs:

One of the simplest and most common causes of flickering lights is a loose light bulb. Over time, light bulbs can become loose in their sockets, causing the connection to become unstable. This instability can cause the light to flicker, or in some cases, go out completely. If you suspect that a loose light bulb is causing your lights to flicker, simply screw it in tighter to resolve the issue.

Reason # 2. Poor wiring:

Another common reason why lights flicker is poor wiring. If your home’s electrical wiring is outdated, damaged, or not properly installed, it can cause problems with your lights. If you have flickering lights and suspect that your wiring may be the cause, it’s best to call in a professional electrician in North Vancouver to take a look.

Reason # 3. Overloading circuits:

If you have a lot of electrical devices connected to one circuit, it can put a strain on the circuit and cause your lights to flicker. To avoid this, try to spread your electrical devices out over multiple circuits, or invest in a surge protector to help distribute the load more evenly.

Reason # 4. Power surges:

Power surges are short-term increases in electrical voltage that can occur for a variety of reasons, such as lightning strikes or problems with the electrical grid. Power surges can cause damage to your electrical devices and cause your lights to flicker. To protect your home from power surges, consider installing a surge protector.

Reason # 5. Electrical issues with appliances:

If you have a large appliance, such as a refrigerator or air conditioner, that’s connected to the same circuit as your lights, it can cause your lights to flicker. This is because these appliances can draw a lot of power, putting a strain on the circuit. If you have a flickering light that’s caused by an appliance, try unplugging it and see if the light stops flickering.

Reason # 6. Problems with the electrical grid:

Finally, problems with the electrical grid can cause lights to flicker. If you experience flickering lights that seem to be affecting your entire neighborhood, it may be a problem with the electrical grid. In this case, contact your local utility company to report the issue.


Flickering lights can be a sign of a more serious problem, but in many cases, it’s a simple fix. By understanding the common causes of flickering lights and taking the steps to resolve them, you can keep your lights shining bright.
