Description and Operation

- Description The ECM (Electro Chromatic inside rear view Mirror) is for dimming the reflecting light from a vehicle behind at night, Preventing glare from the light. The forward facing sensor detects brightness of the surroundings, while the rearward looking sensor detects the strength of the reflecting light and adjusts the reflexibility of the mirror in the range of 7~85%. But, when the reverse gear is engaged, it stops functioning.

1.The forward facing sensor sees if the brightness of the surroundings is low enough for the mirror to operate its function.

2.The rearward looking sensor detects glaring of the reflecting light from a vehicle behind.

3.The ECM is darkened to the level as determined by the rearward looking sensor. When the glaring is no longer detected, the mirror stops functioning.1. LED indicator2. ON/OFF Switch3. Rearward looking sensor4. Forward looking sensor
