Re: Christmas Tree Light Stands

I have some 30' strands of 100 small Christmas cylindrical-like lights. 30'
sections can be plugged into one another. The ends of the strand (cord) have
a male and female plug with two small fuses in each. Each end of the stand
has 2 wires, but when it reaches the first light, then there are three.
What's that all about? Supposedly when lights go out, the rest will remain
on. I've noticed that a stand seems divided into two sets of lights. Somehow
it is possible that both sections can be on, off, or one on and the other
off. How does this happen even though electricity seems to go to the next
strand?

Look more closely, and you'll likely find a third wire that goes from
one end to the other, so the socket at one end is basically the same
as the plug at the other.

Forget about what happens if a bulb blows. If they were in series, then
every time you added a strand of bulbs, all the bulbs would get dimmer.
