Summary
Lights flickering throughout your whole house can be caused by various factors. It may be due to current weather conditions such as high winds and storms impacting power lines. Loose service conductors in your central electrical panel, faulty connectors, worn down wiring, or improperly connected wiring are also common causes.
To stop your lights from flickering, tighten loose bulbs. If your light bulbs are flickering, turn off the power and, using a glove to protect your hand from heat, screw the bulb in more tightly. When the bulb is too loosely inserted, the socket doesn’t make proper contact with the bulb, resulting in intermittent flickering.
A bad circuit breaker can cause lights to flicker. When a large appliance powers on, a bad breaker can cause lights to flicker since it may not handle the sudden high load of current. If you notice flickering lights when a high-wattage appliance starts, a bad breaker could be the culprit.
Diagnosing flickering lights involves checking the connection between the light switch and the bulb. A poor connection at the switch or fixture can cause flickering. Gently wiggling the switch to see if it causes a flicker can help identify the problem. Toggling the switch on and off when the light is already flickering may also resolve the issue.
If your lights are flickering in multiple rooms, it could indicate a loose connection or an overloaded circuit. If the flickering occurs throughout your house, it might be a more serious issue with the wiring. This could be a problem with the electrical panel or the main connections to your home.
Even if the flickering seems harmless, it’s important to address it to avoid potential fire hazards. Flickering lights can be a sign of underlying electrical wiring issues that could present a danger to your home. If the flickering increases or changes in any way, it is recommended to call an electrician for a safety inspection.
Seeing frequent flickering lights may have various causes. While some instances may be related to eye health, such as migraine, epilepsy, diabetes, or Transient Ischemic Attacks (TIAs), others may indicate eye-related conditions. It is advised to have regular checkups with an eye doctor to monitor your eye health.
