the dimming mirror is self-contained unit, the sensors are in the mirror. Just get one from another W140 and give it 12v power.

you could also buy one of those universal dimming mirror (like the ones for Gentex or Donelly? , some of which have built-in compass)... though i don't know what you would do with the IR Remote sensor that is below the MB mirror.

cheers

I have one of those in my 560SEL, Donnelly, I think. Cost me abit over $200.00 for the mirror and $80 to install. It came with a wire to hook up the outside temp and it's mounted right behind the license plate would be. Now I have a reading in F and a reading in C. Replaced the car one because the LCD went bad, and it's from a European car.
BTW, isn't your W140 came with one too?

I just aim mine a bit lower so not reflecting the headlights directly but bright enough to see a car next to me.

In 98 the w140 came with auto dimming driver side mirror.

Rear-view mirror

I am absolutely amazed with the rear-view mirrors in these cars!

I cannot figure out how they make bright lights a dim green . . .

When I first got the car, I thought that the sensor would cause the mirror to tilt down for you; however, the mirror does not tilt at all. It seems, like magic, to tint the mirror depending on how much bright light there is behind you.

My friends think that it works on the same principle as tinted eyeglasses, but I don't believe this is how they operate. Otherwise, why would there be a light sensor?

Can anyone enlighten me as to how the mirror actually dims the light? I am just amazed by it and would like to know how it actually works . . .

Regards,
Bryan

RE: Rear-view mirror

They are 'photochromatic' dimming mirrors. There is a thin liquid like film in the mirror glass, and when the sensor detects glare, the mirror dims, using some sort of reaction (chemical/electrical), but i'm not sure how it works exactly. It's definitely not the same way as the sun glasses though!
