It is just a basic series parallel circuit, so you would get 120V if you got shocked in any case, not an iota safer than the standard series style lights. The only advantage is that you do not lose *all* the lights. I have seen a design where alternate lamps go out when one lamp burns out, rather than 25 or 50 contiguous lamps, but they are a bit more expensive because more wire is needed. BTW.......if your Christmas lights burn out *during* the Christmas season, it means that Jesus doesn't love you anymore. <G> xponent The Beginning Of A New Urban Legend Maru rob _______________________________________________ http://www.mccmedia.com/mailman/listinfo/brin-l
