Buzzing sound from dash when headlights are on...

[240SOHC89]

This just started happening, when i turn the headlights on, or just the position were the signal lights stay on the dash will start buzzing when i hit the gas or hit bumps, also when i shift gears( I have an automatic) it will make the buzzing sound. Im not sure what it is but is very annoying and i dont know what to do, if you have ne idea or have had this problem please answer as soon as you can want to get rid of the sound thanks

I used to hear a buzzing sound when I turned the lights on but it seems to have been corrected. I can't remember what I did to fix it either.

if it's buzzing from your speakers, probably alternator hum. time to get some better grounding

does it sound like the buzzer that reminds you that you left the key in the ignition switch?

Nah, it was just a soft buzz/hum that you could hear if you put your head near the console.
