Lights flicker and dim frequently due to fluctuations in the electrical current, which often indicates an aging or failing electrical system. As various electrical components such as wiring, circuit breakers, and connections naturally deteriorate over time, they can cause inconsistent power delivery, resulting in lights flickering or dimming unexpectedly. Loose or corroded connections increase electrical resistance, thereby reducing the voltage available to lighting fixtures and contributing to these issues. Additionally, older electrical panels may not be equipped to handle modern power demands efficiently, leading to temporary drops in voltage. These problems not only negatively impact lighting performance but also serve as important warning signs that an inspection and potential upgrade are necessary to ensure the safety, reliability, and optimal operation of the entire electrical system.
