Dimmer Switch Makes Lights Buzz

By +Don Vandervort, HomeTips

A dimmer switch can cause a lightbulb’s filament to vibrate, creating a buzzing sound when the light is on a less-than-full setting. You can buy a new dimmer that’s designed not to buzz and replace the switch, but before you do try replacing the bulb with a “long life” lightbulb that has a sturdier filament and is rated 130 volts instead of the far more common 120 volts.
