Flickering lights may seem like a minor annoyance, but they can be a warning sign of serious electrical issues. While some cases of flickering lights are harmless, others can indicate safety hazards, such as faulty wiring or overloaded circuits. Understanding the causes of flickering lights and when to take action can help you prevent dangerous and costly electrical problems in your home. With this in mind, we at JBS Custom Remodeling would like to stress why flickering lights could point to bigger issues.
Common Causes of Flickering Lights
1) Loose or Faulty Light Bulbs. One of the most common and least serious reasons for flickering lights is a loose or faulty bulb. If you notice flickering, try tightening the bulb or replacing it with a new one. If the issue persists, the problem may be more serious.
2) Faulty Light Switch or Fixture. Sometimes, the issue is with the light fixture itself or the switch controlling it. Worn-out wiring within the fixture or a faulty switch can lead to intermittent flickering. If adjusting the switch or changing the fixture doesn’t solve the problem, you may need an electrician to inspect the wiring.
3) Overloaded Circuits. When large appliances—such as air conditioners, refrigerators, or space heaters—turn on, they can cause temporary flickering due to high power demands. While this is common, frequent flickering or dimming could indicate an overloaded circuit. If your electrical panel struggles to handle the load, it may be time for an upgrade.
4) Voltage Fluctuations. Homes typically receive electricity at a steady voltage level. However, if your lights frequently flicker or dim unexpectedly, it could indicate voltage fluctuations. Signs of voltage issues include:
– Lights getting brighter when an appliance is turned on.
– Bulbs burning out quickly.
– Unusual buzzing noises from electrical outlets or panels.
Voltage fluctuations may be caused by issues within your home’s wiring or problems with the power grid. An electrician can check your home’s voltage levels to ensure they are within a safe range.
5) Loose or Damaged Wiring. One of the most dangerous causes of flickering lights is loose or damaged wiring. Over time, electrical connections can degrade, leading to arcing (sparks), overheating, and even fire hazards. If you notice flickering lights along with burning smells, hot outlets, or frequently tripping breakers, turn off power to the affected area and call an electrician immediately.
6) Issues with the Electrical Panel. An outdated or malfunctioning electrical panel can also cause flickering lights. If your panel is old, damaged, or not equipped to handle modern electrical loads, it may be time for an upgrade. Delaying necessary panel repairs or replacements can increase the risk of electrical fires.
