Dimming mirror glass of outside mirror
The electrolyte gel of the mirror glass is actuated by the driver's door control unit depending on the inside rearview mirror request. The crystals of the electrolyte gel react to the control voltage, align themselves in a specific angle and thus darken the mirror glass. Dimming is canceled if the interior lighting is switched on or reverse gear is engaged.
