That image above shows how the lights and power supply are typically wired (not the new LED varieties, though) in traditional Christmas lights. If the filaments of all the bulbs are intact, then the circuit is complete and all the lights work. But if one bulb so happens to break then the entire circuit is broken, thus making all the lights go out. It's basically much cheaper for manufacturers to build lights like this because it allows them to use this cheaper series wiring with inexpensive bulbs.

I hate it when they blow!
They could be done better.. but I think it's done with premeditation. They easily brokes and you buy new ones.. and so on. Pure consumerism.
christmas lights... my greatest nemesis
great info...:)
Wired in series, of course... rather than in parallel. Dumb manufacturers... although... maybe they did that b/c 1 bulb might have overheated and caused the rest to blow :-/
Ugh!!! I hate it when that happens!
magic?
it's easier to wire in series than in parallel and cheaper too.
you learn something new everyday lol thanks for the info supportan yuh
and the manufacturers know that most people will be like "fuckit, i'm not gonna diagnose which bulb it is" and go buy a whole new thing of lights
Guess it's cheaper and easier but it's so much of a pain...glad that the new varieties have gotten rid of this problem mostly it seems.
It's the lazy cheep way, sure...
worse, though. Friend of mine bought a set of LED lights a few months back. Lasted three weeks. had "warning, intended only for short term use" printed on the box. LED lights DESIGNED to fail after a few weeks, instead of the years they should run.
Wow never knew that!
The worst is when your Dad's too cheap to buy a full replacement and you haveto check everyone.
@Das Auto
That's exactly what it is.
bought a prelit tree and had 2 branches that were out right out of the box. I had to search for that 1 bulb and come to find out the bulb was good the wire had just shifted when the bulb was installed but I agree VERY frustrating!!!
Good post. I always wondered why they all go off
Jew here. I don't know what you're talking about ;P
