I finally got a bulb, it is a Wagner 17314, it was crossed with the Phillips 12866 number. It is about 1mm shorter than the Phillips I took out but it will work with a little bending, it flickered when I first put it in so I bent in the contacts a bit. The 6418 was actually about 37mm, way to short. I then did the video camera trick and it worked, the light goes out right-a-way.
