The hidden function of Christmas lights: A trick few people know about

Oftentimes, extra red bulbs are found in a box of Christmas lights. If they're not simply spares, what can they be used for? It turns out a simple trick can completely transform your Christmas tree's appearance.

Swapping out one of the regular bulbs with a red one alters the illumination of the entire string of lights - causing them to flicker. It does take a moment for this change to take effect, as exhibited by TikTok user @viznelly.

It's worth mentioning that with newer light sets, changing the light behavior is typically more straightforward - often achieved via a remote control included in the set. Regardless, @viznelly's video has been a hit, with over 1.8 million likes and more than 20 million views in the year since its posting.

Several commenters have reacted with surprise, and even joy. However, for many, this revelation wasn't anything new. "Watching the younger generation discover things from 50 years ago is like watching grandparents learn Snapchat," one commentator jested.

As for when we decorate Christmas trees, tradition suggests the morning of December 24 is ideal. Currently, it is also one of the most popular days for people in Poland to adorn their Christmas trees.

The date of December 6 is also frequently noted as the day Christmas trees are brought into homes. This is Saint Nicola's Day, a holiday that marks the start of pre-Christmas preparations for many. The Catholic Church suggests another date, recommending that the Christmas tree be set up a week before Christmas Eve.

In the coming days, many individuals won't just be decorating their homes, but also embarking on their Christmas shopping. It's worth mentioning that on Sunday, December 10, shops will be open. The next shopping Sunday falls on December 17, 2023.

The penalty for violation of the Sunday trading ban ranges from $250 to $25,000, and repeatedly breaking the law can result in more severe penalties.
