Does anyone know where I can buy a chromatic/auto dimming mirror kit for a car?

Does anyone know if the sell upgrade kits for chromatic/ autodimming mirrors on cars? I've tried searching the net for it but with no luck. Anyways, I've got a car with the dimming mirrors it's just my exterior ones only slightly dim and I'd like to upgrade them to some that dim darker...any ideas? Also I've got another car without dimming mirrors and I'd love to be able to upgrade it with some kind of mirror kit.

Thanks

I was wondering the same thing. I'd grown accustomed to them on my old car.
