Flickering Lights
Although you may believe that flickering light is caused by a faulty bulb, it could also be an indication of a more serious electrical problem, such as faulty wiring or a faulty circuit breaker. When you notice a light flickering, the location of the problem can help you figure out what's causing it. Multiple flickering bulbs in a single room indicate a problem with the circuit breaker in that area of the property. Flickering lights throughout your home indicate a problem, such as loose conductors in your central electrical panel. Lights blinking when you turn on a large appliance indicate that the device is putting too much strain on your central circuit breaker.
In each of these situations, you should contact an electrician to assess the situation and address any potential safety concerns. If you want to buy a home warranty policy, look for companies that include lighting fixtures as part of their coverage.
