Essential, the interior rear-view mirror is a device that allows you to drive safely. There is, however, a small hidden lever underneath this accessory, that many people are unaware of even exists. Still, it is proving to be very useful.
Many people think they know their vehicles by heart. However, they often miss out on some very useful devices. This is the case of the small lever hidden under the interior rear-view mirror.
There is no denying that using the rear-view mirror during the day is much more pleasant than at night. Indeed, although its presence is not trivial, this small lever promotes a much more comfortable night driving. In this article, we will see concretely what this hidden option on the rearview mirror is for.
What is the function of the lever below the interior mirror?
Before you start driving, note that it is important to adjust your rear-view mirror to your size and position. If you are bothered by the bright lights of the cars behind you, you can use the small tab under the rearview mirror. Bright lights can cause accidents as they obstruct visibility.
This small lever allows you to protect yourself from this reflected light. You can switch from daytime to night vision with a simple gesture. After activating it, the field of view does not change.
Unlike exterior mirrors, the interior mirror consists of a glass and a mirror. In the foreground is positioned the glass while the mirror is positioned behind, so that it can be tilted. In night mode, the window and mirror align with the same orientation to prevent the driver from being bothered by the brightness reflected on the rear-view mirror.
Older car models only have the function of manual dimming, which until then has proven to be very effective.
For newer cars, the interior mirrors have an automatic dimming function. This device has not been a dream for the future for many years. You can find them in factory settings in some cars, usually high-end, as you can get from specialized sellers. These mirrors increase safety while driving by dimming reflected light. Advantage! This function is integrated and triggers automatically, so the driver does not have to take any action.
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 of the rear is greater than that of the front, the rear-view mirror is automatically dimmed. The mirror darkens thanks to a so-called electrochromatic layer. This is attached to the glass of the retro and has electrolyte crystals. This technology is similar to that of LCD screens and smartphones. In addition, the advantage of this function is that the position of the mirror does not change.
The lever below the rear-view 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.
