There are a few potential causes of flickering lights throughout your home. One possibility is that there is an issue with the wiring in your home. If the wiring is old or damaged, it can cause the lights to flicker. Another possibility is that there is a problem with the circuit breaker. If the circuit breaker trips frequently, it can cause the lights to flicker. Finally, if you have fluorescent light bulbs in your home, they can sometimes flicker when they are first turned on.
