Six to eight years ago I bought two new Lionel Legacy GP-7 diesels (6-28340, 6-28570). The front and rear headlights have never worked. I once was bold enough to take the body off one of them to look for a loose or broken wire, but nothing looked amiss. Since it happened to both, out of the box, I wonder if this is a known problem with a known solution. Any clues about possible easy fixes?
