3rd brake light rattle

i just dumped a bumpin' system into the trunk of my 95 coupe. no i've got this bad rattling sound. you can't hear it from the front seats, but in the back seats it's audible and from outside behind the car it's really bad. i've located that it's the 3rd brake light rattling against the rear window. does anyone know how i could make it stop rattling? thanks

I wish I had my sis's '95 DX coupe here to look at for referance, but if I remember right, the 3rd brake light in 5th gens is a SEPERATE part from the rest of the rear shelf. I could be wrong on that though, since on my 6th gen Civic coupe, my 3rd brake light is integrated into my rear shelf section. Anyways, what you want to do is get some foam tape, and line the border of the light with it where it touches up to your rear window, doing that will get rid of the rattling it creates.
