Why is my light bulb buzzing and flickering?

If your light bulbs are flickering, turn off the power and, using a glove to protect your hand from heat, screw the bulb in tighter. Loose light bulbs mean the socket isn’t making proper contact with the bulb, and that can cause intermittent flickering. Even recessed lights can loosen, so check those connections first.

Take one or two bulbs out of the fixture if it is a multi-bulb light. Check whether it still hums. If not, this means that your dimmer can’t handle the wattage of running all the lights at once. Replace the dimmer with a higher-wattage product, or replace the light bulbs with lower-wattage bulbs.
