there's another posts titled "blown mirror light", or something like that, that has instructions on how to remove the casing around the mirror. I tried the other day, but I don't think I gave it enough elbow grease. I wanted to see if anyone here has tried it successfully before I give it a go again. Just don't want to break the catches, as the outer case isn't cheap to replace. Don't know anything about whether you need resistors for those lights.
