Restoring Vintage Christmas Lights

At my parents' place, there was a Christmas lights string that I admired since childhood, even though I couldn't recall ever seeing it whole and functional. I always wanted to see its glow and charm when it was lit up. 🌟

The light was in dreadful condition: not all lamps were present, wires were cut, and only a few lights were working. I decided to "refactor and rebuild" it completely but to save as many original parts as possible.

So, my exciting journey started with the task: replace glow-lamps with LEDs, and, consequently, replace the supply voltage from 220v to 5v.

We Wish You a Merry Christmas
