We had a spotlight positioned where we could not get to it without risking breaking brittle old roofing or suffering a bad fall. I tried other things, but they didn't work. I tried this and the light was out and replaced in five minutes, only needing a little inward pressure to break the grip of 15 years corrosion. Inserting a new bulb was even easier. If you've got a bulb in a position you can't get at this is the way to go.
