Flickering lights tends to trigger thoughts of Halloween and scary movies, which is understandable enough. The thing is, sometimes, people end up dealing with this well beyond any fictional spooky setting. 

However, the fact is that flickering lights are beyond inconvenient: they’re a sign of an underlying electric problem. Statistics have shown that electrical fires in homes count for well over $1.3 billion in terms of property damage. 

Meanwhile, fatalities also go all the way up to 500 each year. Homeowners should address electricity issues immediately since it can make all the difference in you and your family’s well-being and safety in the long run.

What Are the Causes of Flickering Lights in the First Place?

Flickering lights, in the broad overview sense, are what happens when there’s fluctuation or reduction in the total voltage of a household. Read on to learn about common causes:

Dimmer Switches

Flickering LED bulbs tend to become faulty when dimmer switches are involved. Most of them can handle high electrical loads as it is. So low-voltage LEDs can flicker or dim if they’re connected to dimmer switches of a higher power. 

You must consider the compatibility of bulbs and dimmers before making any purchase. Moreover, you can replace dimmer switches with those meant to take on LED bulbs in the first place.

Malfunctioning Connections

Connections can get rather concerning within the on and off switch of fixtures or in a lamp or light. In that case, flickering will likely ensure. Simply wiggling the on/off switch can help to determine whether there’s a connection issue at hand. 

Does your light dim as you wiggle the on/off switch? No doubt there’s a bad switch in place, then. While switch replacement seems easy enough if it’s along the lamp cord, those integrated with a socket are best left to the experts for safety reasons.

Large Current Draws

When you have major appliances in your home, a number of them can pull at least 100 amps from your wiring as they cycle. The sudden power surge leads to the lights either flickering or dimming even for a moment. 

To avoid heavier issues, you will likely need an electrician to check in on your apparent wiring concerns. The problems could very well date back to how appliances are wired in general. In some cases, the circuit ends up being overworked in itself.

Unsecure Bulbs

If a bulb is loose, it will end up rattling within the socket. Inconsistent connections can appear as a result, alongside flickering regularly. 

Changing or tightening the bulb is the usual quick fix, which helps to establish a strong bond. That way, you can avoid any glitches in the electric current of your house and keep you and your family safe at all times.


Flickering lights are often associated with all things scary, but there’s a real-life reason to fear them as well. Electricity plays a vital role in the safety and functionality of a home overall. Common causes include loose bulbs, large current draws, faulty connections, and dimmer switches.
