Many people think they know their vehicles by heart. However, some very useful features are often missed. This is the case of the small lever hidden under the interior mirror.
It cannot be denied that using the mirror during the day is much more pleasant than at night. Indeed, although its presence is not negligible, this small lever favors a much more comfortable night driving. In this article we will see what this hidden option in the rear-view mirror is for.
What is the function of the lever under the interior mirror?
Before you start driving, please note that it is important to correctly adjust the mirror to your height and position. If you are bothered by bright light from cars behind you, you can use the small tab under the rearview mirror. Bright lights can cause accidents as they obstruct visibility.
So this little lever allows you to shield yourself from this reflected light. You can switch from day vision to night vision with a simple gesture. After activation, the field of view does not change.
Unlike the exterior mirrors, the interior mirror is made up of a glass and a mirror. The glass is placed in the foreground while the mirror is placed behind, so that it can be tilted. In night mode, the glass and mirror are aligned in the same orientation to prevent the driver from being disturbed by light reflected from the rearview mirror.

Auto Dimming Mirrors
Older car models only have the manual dimming feature, which has proven to be very effective so far.
For newer cars, the interior mirrors have an auto-dimming feature. This device has not been a dream for the future for many years. You can find them from the factory in some cars, usually high-end, since you can get them from specialized sellers. These mirrors increase safety while driving by attenuating reflected light. Advantage ! This function is integrated and is activated automatically, so the driver does not have to do anything.
Auto-dimming mirrors are equipped with two sensors that measure the incidence of light and detect the difference in brightness between the front and rear of the car. If the incidence of brightness from the rear is higher than that from the front, the mirror automatically dims. Therefore, the mirror darkens thanks to a so-called electrochromatic layer. This is fixed to the glass of the retro and is equipped with electrolytic glasses. This technology is similar to that of LCD screens and smartphones. Also, the advantage of this function is that the position of the mirror does not change.
The lever located under the mirror is not there for no reason. As you will have understood, this is a very important safety device to ensure the safety of drivers.
