So my family uses a vintage angel tree topper. One of these

It's an old one, seen a lot of Christmases, but this year it wouldn't light up. And the plastic on the sockets is so old and brittle they were falling apart. So I completely rewired it by taking a 20-light strand, cutting it in half, replacing everything and tying it back down, and twisting the two severed ends together with a blue wire nut and electrical tape so it couldn't come loose. Angel lights up, all good and fine.

Not an hour later, and it's burnt out again. Not exactly what you'd expect from a brand new strand of lights. However the cord of lights it was plugged into is still active and showing no signs of burnout occurring.

Now the question is, what exactly did I do wrong here, that would cause this to happen?
 
Some Christmas light strands are wired in series. They are dependent on having the resistance of all the light in place. Essentially, if you cut one of those in half, you double the voltage going into the remaining lights and they don't last long.
