Thanks for the replys boys!
I already plan to plug them into a GFCI & it is already installed.
What my concern was, is that on the first leg of the first bulb 110v is present and because its so wet during the winter here the first bulb could become live to touch when sopping wet, but I guess even at 110v the ligths are safe for outside use even in the wet otherwise they would not manufacture and they would not list them. The GFCI would only trip out if someone was to actually touch the bulb as I don't think the hedge would act as a good enough path to ground for the GFCI to operate.
