Before I started filing, I put them on the base one more time to make sure I knew what/where I was sanding and the bulb rotated right into position. When I went to do the second bulb, it looked again like it was going to need sanding, so on a hunch I took the bulb off and rotated it 180 degrees, and put it back on the base and it slid right into place. For reference, the bulbs I was using were the Amber WeissLicht bulbs.
It looks like the tolerances on these LED bulbs varies just enough to cause problems.
