I like the electrochromic mirror but I wouldn't mind if it darkened a bit more in response to headlights in the mirror at night. Thus, I was interested in this page from John's site where he says "Modified the Electrochromic-Mirror so it would get darker at night" as the caption to a picture that appears to show the back of the mirror with a piece of blue paper (?) taped onto it. Can John or someone else fill us in on what he has done and how well it works?

we discussed it somewhere. I couldn't find the thread, but it basically was some kind of plastic, he made it sound almost like a tarp material. Since the mirror ir black though, I was thinking maybe even a small square from a black trash bag or something?

Here's detail about what I did...

It's pretty simple, just a piece of transparent plastic was added to fake the secondary sensor into thinking it was darker outside.

Thanks, John. I think I'll have to give that a try. Where'd you get the transparent blue sheet plastic?

It probably doesn't matter what color. The blue is just what I stumbled upon in the office supply section at Target. It's actually part of a "reusable envelope".

From the outside of the car, it's almost completely invisible anyway. The glare from the windshield conceals the mod pretty well.

My rear window is tinted. I hardly ever get hit by lights that are too bright, even if I'm being tailgated by a "bright-light-bob".

So if you were wondering.....if you are planning to tint your windows, you may or may not need the mod.
