Alarm LED to Rear View Mirror

Can someone HELP ME PLEASE!!!I am trying to accomplish this, I'm trying to put my Alpine alarm LED on the bottom of my rear view mirror ( kinda like middle on the left half of drivers side of the mirror ) I think BWMs have a red LED on theirs. I have a 1991 Supra turbo, and when I removed the mirror to view it, I just cannot seem to find a way to open it up???? I was only able to move the 'attachment arm" that attaches it to the roof of the car, but that's it! Can you offer any suggestions? You can reply to me here: sheldonassing@hotmail.comThanks a million, in advance! Sheldon :)

you can pop the glass out.. sometimes they break, sometimes they don't.. if it breaks you can cut a piece of mirror plex to replace it.. JUST BE SURE TO WEAR SAFTY GLASSES!!!!!
