Anyone who drives at night in the car will find that the headlights of the vehicles behind in the rearview mirror can be extremely dazzling. The lights make it almost impossible to see in the inside mirror and dazzle enormously. There are, however, helpful techniques against glare from the headlights in the rearview mirror. The rear-view mirrors can be tilted for the purpose of dimming. This can be operated manually and ensures that the mirror tilts into a position that only partially reflects the light and at the same time provides a sufficient overview. This means that even after the dimming, the driver can still see exactly what is happening behind him. While manually dimming rear-view mirrors offer a certain level of convenience and increase safety, there are far more convenient solutions.
Dim the rearview mirror - automatically
Automatically dimming interior mirrors have not been a dream of the future for many years, but are widely available ex works and also from specialist dealers. The articles can increase safety while driving and the driver of the vehicle does not have to take any action himself. The automatically dimming rearview mirrors have two photo sensors that precisely measure the incidence of light. The sensors detect the difference in brightness between the front area of the car and the rear area of the car. If the incidence of light from behind is greater than that in the front area, the interior mirror is automatically dimmed. The dimming is done by darkening the mirror slightly. The darkening is created by a so-called electrochromatic layer. The layer is attached to the glass of the rearview mirror and is equipped with electrolyte crystals. The technology is similar to the functionality of cell phone or television LCD displays.
Stopping down by darkening
If an electrical voltage is applied to the electrochromatic layer, the uniform electrolyte crystals will align themselves at a defined angle. The result is a stepless darkening effect. The darkening of the mirror depends on the sensor measurement and the incidence of light. The advantage is clearly that the driver of the vehicle does not have to dim the rearview mirror manually. Both hands can stay on the steering wheel, which also increases safety.
Retrofit automatically dimming interior mirror
Interested tuners can retrofit their vehicle with an automatically dimming rearview mirror. Various retrofit kits for certain car brands are available from specialist retailers. The product description should be read carefully before buying, as certain vehicle types require further conversion measures for retrofitting. The automatically acting mirrors can also be found under the keywords "Interior mirror automatically dimmable". The interested tuner can find suitable models for retrofitting a VW, for example. For example, the mirror is available for the VW T6 and VW Caddy & Co. When buying, however, you should not only pay attention to type compatibility. By the way, the technology and the functional principle of the automatically dimming exterior mirrors are identical. They are also available for retrofitting on request. If an automatically dimming interior mirror was ordered directly from the factory, the cables for controlling the exterior mirrors are usually already in the vehicle. Then it might even be enough if you just swap the glass. Here, however, the individual case and the vehicle decide. In any case, it is possible to retrofit an automatically dimming exterior mirror and interior mirror for almost all vehicles.
