I see them in Deadly Dave's thread, Gadge, I've even heard of that kind of bearing before, I just didn't associate them with that problem.
Iceman, Dave's machine was an early one, with a long clutch shaft running the whole width of the frame. This seems to have resulted in excessive span between the bearings, causing fatigue failure of the shaft. For quite a few years now Greenfield have used a short shaft design, with the clutch shaft only about half the width of the frame, and the battery placed in the space saved. I haven't heard of a short shaft machine breaking its shaft, so Dave's problem isn't likely to happen to you.
I suggest you try to find a pair of LED lights that will fit into the existing recesses in the front end panel of your machine. This will look much better, and be much easier to fit. As Gadge said, reversing lights may be the easiest way to do the job, since the lights you currently have are also reversing lights, so you can probably find something made as an aftermarket replacement for them.
