What about the little black spots on the mirror?

In this case, the mirror should be replaced because the welding slag has damaged the mirror. It is recommended to get some washing powder and detergent to clean together. The rearview mirror must be kept clean and cleaned frequently to have a good view.

Compared with the hidden danger caused by blocking the line of sight, rearview mirror is one of the important safety components of motor vehicle body, which is used to observe the road conditions behind the car when reversing and the driver's observation of the whole car during driving.

Mirror image definition

The anti-glare reversing mirror is generally installed in the carriage, which consists of a special mirror, two photodiodes and an electronic controller. The electronic controller receives forward light and backward light signals sent by the photodiode. If the lighting lamp shines on the mirror in the car, if the rear lamp is larger than the headlight, the electronic controller will output a voltage to the conductive layer.

The voltage on the conductive layer changes the color of the mirror electrochemical layer. The higher the voltage, the darker the color of the electrochemical layer. At this time, even if strong light shines on the rearview mirror, it will appear dark after being reflected on the driver's eyes by the anti-glare rearview mirror, and it will not be dazzling.
