appreciated the comments, I've not given up yet, reason being, the lights are not available anywhere as pre wired mains outdoor, they are flame (flickering) effect post lights, I've spent hours trying to find them as mains pre wired, they don't exist, and they are what she who must be obeyed wants!
To elaborate further, my simple thinking:
1.2v so lightweight wire, they would be plugged in indoors, so the transformer or whatever would not be outdoors. The rechargeable cell would be removed, is it worth the effort, I dpont mind the work, but dont want a potential fire!
