With Christmas Day creeping upon us, many may be starting to take their trees out of the loft and put them up for display in their living room. Meanwhile, others may have had theirs up for weeks.
Upon the scramble of looking through decorations and lights, you most likely will have stumbled across a small red light bulb and have been left clueless about its purpose.
Many have claimed that they believe the small red light to be a spare bulb or a replacement. However, a woman has shared the red light’s proper use and it’s game-changing for festive décor.
Taking to TikTok, a woman explained the little-known use of the small light and her demonstration has rocketed in views online.
Her video, which was shared to the popular video-streaming service, has surpassed a whopping 19.2 million views since posting.
The woman shared a demonstration of her putting the light to its intended use. You start by simply removing a single bulb and replacing it with the red one.
“Remove regular bulb and replace,” the TikToker advised in her demonstration.
The extra light is not only different in colour from the rest, but it also gives the string of lights a flickering effect rather than using a modern day remote.
The woman admitted: “I was today years old when I found out what these are for.”
Flocking to the comments, viewers shared the surprise in their thousands – with several admitting that they thought it had a different use entirely.
One person claimed: “I thought they were spares.”
A second added: “Wait what??????? I thought they were replacements!”
A shocked third used wrote: “I swear to god this app has taught me more in the last year than I have been alive.”
Meanwhile, a different user commented: “Dude all they had to do was write that somewhere on the box. I wasted so many years not knowing about this.”
“NGL I’m embarrassed that I didn’t know this,” a fifth added.
Meanwhile, other people claimed that they’ve been aware of the little-known use for decades.
One person said: “As someone who grew up in the 90s…I thought everyone knew this – We didn’t always have remote control lights!!”
A second agreed: “I used to put up the Christmas lights at my parent’s house, so I didn’t know that this wasn’t common knowledge.”
