True, there's always failure points. But with LEDs (at least the LED strings I would bother with), dead bulbs don't kill parts of strings, so you always know when a single bulb has died. If a string dies on LED, that's nature's way of saying "replace the whole thing". With my current strings, I had to run down the rabbit hole to come to the same conclusion.I have several strings of LEDs that only partially light up anymore, and I've come to the conclusion that the thin wires running to the plastic sockets has broken somehow. So not all is goodness and light with, uh, lights.
