If it was a short then the fuse would blow. It could be a damaged wire or corrosion in the light bulb socket.

It's weird though, It will work for 2-3 months then randomly go out, for a week or so then start working for a month or two at a time again. Its not the first time this has happened.

check the plastic wrap on the wire harness that feeds the light and look for a crease. remove plastic wrap to a point below crease. solved this problem on both my 2000 and 2005 f250s after changing left rear brake light several times.
