Why Do Each of the Christmas Lights Go Out When Just one Bulb Blows? [ChristmasLights]

In case you’ve dabbled in Christmas decorations with traditional Christmas lights, you’ll know that after one bulb blows, the full line goes out with it. Why is that? As a consequence of how the manufacturers wire them.

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

If you’re inquisitive about finding the borked bolb and doubtless salvaging the lights, you’ll must perform a binary chop. Those instructions may well be found here . [ JGC.org via MAKE ]
