Many thanx, Mechnut - that's what I was thinking and hoping! I know your voltages and things are different, but I believe the priciples are the same. Based on that, I think I may go with an earth (or 'ground', as I think you guys call it) just to be on the safe side. Do I just solder it to the corner of the bulb guard somehow? (and yes, the place is 'grounded')
