I have been searching the internets looking for what the hell this thing is really called. It is a small box that you can wire lights into, and it has a microphone on it and as it picks up the bass from music it makes the lights flash/strobe/pulse with the music.

I know there are such devices because my friend has one but there is no name on it.

WHAT IS IT CALLED, AND GIVE ME A WEBSITE THAT SELLS THEM!!!!!!

 

Used to have one back in the old days. They are called a light organ.

That would be groovy in a truck. How about adding a disco ball as well?
