Drivers urged to use car's 'life changing' secret button under mirror that most people don't know about

It seems everyday people are finding out about mysterious buttons or hacks that are making their life as a driver easier.

Whether it's defrosting a Tesla or uncovering a secret extra key, it's like we're learning new things about our cars every day.

And thanks to TikTok educating the public, here's another gem: a button hiding under your car's rear-view mirror that might just be a lifesaver. Now, some of you might already know about it, but for those who don't, it's definitely worth knowing.

The clip, from @everythingbrooklyn captioned: 'Me flipping the rear view mirror tab so the headlights don't blind me' shows the woman revealing the handy use of the hidden button.

She demonstrates how pressing the small tab underneath the rear view mirror flips the mirror in a different direction. This essentially reduces light glare, since the light is directed down past the eye instead of into it.

Some viewers claimed they knew about this feature all along, writing things like: 'i thought everyone knew this' and 'i thought this was common knowledge tbh.'

Others were surprised and happy to come across the informative clip.

One wrote: 'i didn’t know about this either until a few weeks ago and my life has been changed ever since.'

Another replied: 'learn something new every day'.

Whereas, a group of other users were more impartial and said that whether or not you have the button depends on the model and make of the car.

Users are saying that if your car doesn't have the tab, most likely it is a newer model and the mirror is an auto dimming mirror.

One TikToker explained: 'K so my car has an auto dimming mirror & it dims the mirror based on how bright the car behind me is.'

Many car manufacturers have introduced brighter beams on vehicles to increase visibility on the roads. Whilst this is all good and well for the driver, other road users can be blinded by the brightness of the lights - leading to potential accidents - according to the National Highway Traffic Safety Administration (NHTSA).

These anti-glare features are designed specifically to work against ordinary headlights so don't expect it to work for extremely bright beams like the sun.
