I brought my car into honda because I kept hearing a light squeeking sound everytime I drove over a bump, big or small. I thought it was my goldline springs or something that went wrong during my lowering, but the honda tech told me that the sound was coming from my right taillight.

i didn't believe him at first, but he pounded the light a few times and it made the same squeeking sound. I had altezzas on at the time, so they said that they wouldn't try to fix it. I went home and put my stock tails back on, tightened them as hard as I could, but they still squeek.

Anybody here had this problem before? Any suggestions on what to do?

What the heck? Strange thing you got going on there.

Have you tried putting a layer of Dynamat or Fatmat between the tailight and car's body?
Should kill the noise.

whoa that is weird, i never knew tail lights could squeek
