2000 Nissan Xterra Light Bulbs

I bought 4 of these for the interior of my 2006 Nissan Xterra SE 4X4. I was able to install the first two in the front overhead, and they worked fine. I then replaced the center area light and when I turned it on, all lights in the cab went out. Apparently I did not realize that you could not install them with any of the interior lights on, but it was night and I could barely see what I was doing without having the front interior lights on. They blew the fuse which in an Xterra is not a simple matter. There are micro fuses in the glove box area, but no one seems to know which one controls the interior lights, which also include the key hole light. There are other fuses under the hood, but all of those appear fine. Trying to find which fuse blew is the next task, but I havent had time to do it yet. I know now that I cannot have these bulbs in when I replace that fuse, and I cannot turn any of them on until all are installed. There are no instructions with these bulbs, so take my word for it. Do not have any of the interior lights on when you replace these bulbs, and be prepared for a blown fuse if you accidentally turn one on before you install them all. It's a real pain in the *ss you don't want to experience!!!
