What Causes Flickering Lights In My House?

Flickering Lights Can Have Many Causes

Flickering lights in a house can be caused by a variety of factors, ranging from minor issues to potentially more serious electrical problems. Here are some common causes of flickering lights.

Loose Bulbs or Poor Connections.

Sometimes, flickering can simply be due to loose light bulbs or poor connections in light fixtures. Ensure that all bulbs are securely screwed in and that the connections are tight.

Faulty Bulbs

Defective or low-quality light bulbs can flicker when they are nearing the end of their lifespan. If you’ve ruled out other causes, try replacing the flickering bulbs with new ones to see if that resolves the issue. Some of the new LED light bulbs can be defective. Try changing out bulbs first to see if this solves the problem.

Voltage Fluctuations

Variations in the electrical voltage supplied to your home can cause lights to flicker. This can be due to factors like heavy electrical appliance usage in your home or fluctuations in the power grid. In some cases, the voltage from the utility company might not be stable.

Circuit Overload

If a circuit is overloaded with too many devices or appliances drawing power simultaneously, it can cause lights to flicker. This is more likely to happen in older homes with outdated wiring or insufficient electrical capacity.

Loose Wiring

Poorly connected or frayed wiring within the electrical system can lead to flickering lights. This is a potentially dangerous issue that should be addressed by a licensed electrician, as it can pose fire and safety risks.

Dimmer Switch Issues

If you have dimmer switches installed for your lights, flickering can occur if the dimmer switch is incompatible with the type of light bulbs you’re using or if the dimmer switch itself is malfunctioning.

Faulty Light Fixtures or Switches

Defective light fixtures or switches can cause flickering. This could be due to issues with the internal wiring of the fixture or switch.

Weather Conditions

Extreme weather conditions, such as lightning storms or heavy winds, can cause power fluctuations that lead to flickering lights.

Electromagnetic Interference

Certain electronic devices or appliances, especially those with large motors, can generate electromagnetic interference that affects the operation of nearby lights.

Bad Electrical Connections

Poorly installed or damaged electrical connections in your home’s wiring can lead to flickering lights. This is another issue that should be addressed by a professional electrician.

Flickering Lights Can Be A Sign Of Bigger Problems

If you experience persistent or worsening flickering lights, especially if it’s accompanied by other electrical problems like tripped circuit breakers or outlets not working, it’s best to consult a licensed Colorado Springs electrician. Electrical issues can pose safety risks, so it’s important to address them promptly and professionally.
