A secret switch under the rearview mirror in many cars could save lives, with some drivers only now finding out that it exists. According to the RAC, nine out of 10 drivers think that some or most headlights are too bright and 90% of them say that they get dazzled.
The Government has been looking at regulations for brighter new LED lights. Transport Minister Baroness Vere recently said in Parliament: "Regulations are already in place to help prevent headlamps, including those using LED technology, causing dazzle and glare. Nevertheless, work is ongoing at an international level to develop and introduce improved headlamp aiming requirements. These are also likely to mandate automatic headlamp levelling systems on new cars."
But there is also already a solution that could help - at least with the glare from cars behind you reflected in your mirror.
One TikTok user, @everythingbrooklyn, demonstrated the button in a video that has garnered over two million views and over 96,000 likes.
"Me flipping the rear view mirror tab so the headlights don't blind me," she captioned it.
Underneath the rear view mirrors of many cars is a small tab that, when flipped, angles the mirror in a different direction so that the beams of light don't hit it the same way.
That essentially reduces the glare, since the light is directed down past the eye instead of into it.
Many TikTok users flocked to the comments section to express their shock at discovering the feature existed. @natbr24 wrote: "I didn’t know about this either until a few weeks ago and my life has been changed ever since."
"Never knew that’s what that little tab thing is for," wrote @regan.piercee.
Others, however, were quick to tease the people who didn't already know about it.
"How did none of you know this," wrote @gr3y5999.
@oliviaaa.615 said she thought everyone knew about the feature.
