Why do the lights in my bathroom make a faint buzzing sound when I switch them on?

Question

When I flip the switch, the 3 bulb light fixture above my sink makes a very annoying buzzing sound. Why?

Answer 1

if they are florescent,then it is the ballast,and if not get an electrician,because something is wrong.

Answer 2

THE 3 BLUB FIXTURE CAN NOT BE FLOURSECENT UNLESS ONE IS MISSING AND THEN IT MAY MAKE NOISE. DOES THE LIGHT DO ANY FADING IN AND OUT? IF U WIGGLE THE SWITCH DO THE LIGHTS FLICKER OR FADE IN AND OUT? THE BUZZING SOUND COULD BE A LOOSE WIRE. ARE U A DYI PERSON? IF SO, THEN CHECK IT OUT AT SWITCH AND LIGHT FIXTURE. IF NOT CALL AN ELECTRICIAN.

Answer 3

That buzzing sound that you hear is the electricity going through the light bulb, or its about time for it to burn out

Answer 4

If they are not fluorescent,and they are regular bulbs, they should not be making any noise. Since they are making a buzzing sound,something is loose. Have someone look at it. It wont go away by itself.

Answer 5

I actually have heard dimmers humming before. no longer all that unusual or risky. Its only a rheostat contained in the dimmer unit. Assuming he became an approved electrician, you have to be fantastic. on to the bulbs. what's a 100W gentle bulb adapter? under no circumstances heard of this manner of beast.

Answer 6

it sounds like you have something loose either the bulb isn't screwed in good or you have a loose bulb.

Answer 7

All flouresent bulbs to that when you first turn them on.

Answer 8

you've got a bad connection and its grounding out.I would have and electrician or friend who is handy to look at it

Answer 9

they are trying to tell you something.
