Electro Chromic Inside Rear View Mirror (ECM)
1.The ECM (Electro Chromatic inside rear view Mirror) is one that automatically dims to protect the driver’s eyes when it senses light reflecting from the car behind.
2.The sensor in the mirror detects the brightness and if the headlight from the car behind is reflected on the mirror, the chemical layer inside the mirror reacts to glare and adjusts the reflectivity from 10 to 70%.
3.When switching to the reverse gear, the mirror becomes bright regardless of the surrounding.
4.The ECM (A) receives voltage, ground and gear signals, it then measure the glare intensity to adjust dimming.
