Flickering lights are annoying and may be a sign of a potentially dangerous electrical problem or something simple-like a lightbulb that's on the fritz. If replacing the lightbulb in question doesn't work, call an electrician right away. Your flickering lights could be the result of loose wiring which may lead to an electrical fire. It is best to be safe and rely on our electrical professionals at Wiremen Electrical, to assess the situation and prevent future damage!
