The answer to 'surge protector dimming lights' is that a surge protector can sometimes cause lights to dim or flicker. This is usually due to the surge protector's internal components filtering or limiting the electrical current, which can affect the voltage supplied to the lights. Symptoms may include lights dimming, flickering, or pulsing when other appliances are turned on or off.
In most cases, this is a normal function of the surge protector and not a sign of a more serious electrical issue. However, if the dimming or flickering is excessive or persistent, it may indicate a problem with the surge protector or the electrical system. If this is the case, it's best to call a licensed electrician to inspect the situation and make any necessary repairs or replacements.
