Your electrical system is complex and contains a number of different types of appliances and fixtures, but the most numerous and arguably important fixtures in your electrical system are your home's lighting. Lights that are chronically flickering are a clear indication that there could be something wrong with your electrical system, which can pose safety risks to your entire home. Being aware of some of the most common causes of flickering lights in your home and what you can do to fix them can make it easier for you to address issues before they grow to be serious.
One of the most common reasons why your lightbulbs are flickering is because of their age and condition. Older bulbs that make use of filaments can begin to flicker normally as they reach the end of their lifespan, eventually dimming or burning out entirely. While replacing these lightbulbs can restore the steady flow of light in the affected room, in order to eliminate the flickering problem entirely, consider switching from filament bulbs to LED lights, which will simply die once they have burned out.
However, if replacing your lightbulbs did not remove the flickering problem, the issue likely lies somewhere else and could be more serious. Homes that have older wiring or that have had additions and renovations since they were first constructed may not have the electrical capacity to handle all of your light fixtures and appliances running at once. If you notice that your lights flicker or dim when other appliances turn on, such as the dishwasher or fridge, your wiring may be overloaded. If this is the case, you should talk to an electrician about upgrading your current wiring system so that your lights and other electrical outlets are receiving an adequate amount of power.
Beyond issues with your lightbulbs or your wiring, it is also possible that the fixtures that your lightbulbs are screwed into are suffering from mechanical issues or improper installation as well. Loose fixtures will provide a tenuous connection with the lightbulb, which means that a proper flow of electricity has not been established. You will likely also find that these fixtures generate a lot of heat. This is a serious issue if left unaddressed, as damaged fixtures can lead to electrical fires and damage within your home, and they should be inspected by an electrician to see what the next best steps are in terms of repair or replacement.
