Can someone tell me what that light does? There's a little swith on the bottom of the rear view mirror, I can press it, and the green light on the mirror will go off.
But I don't know what it's for. Any ideas?
Thanks,
Joe

 

What year? My '00 had an LED that came on when the auto- dimming mirror was swithced on.

 

Yeah, that light and switch is for the auto-dimming mirror. Lit = on.

Always thought they were kinda overkill with the tinted windows and all. My new Excursion (XLS) doesn't even have it. Just the traditional flip mirror.

 

I like that auto dimming mirrior alot. It saves you from the glare when people like to drivebehind you with there brights on. I wish they used those on the towing mirriors

 

Ya, who's going to be the first to finally dim side view mirrors - they have them on cars so why not on our gargantuan truck side mirrors.

I was glad to see the auto-dimmng rear view mirror on my 00 X but find that I hardly need it probably due to the height of the truck and the privacy windows out back.

 

My '98 'Burb had the chromatic outside mirrors and I'll tell you that it really surprised me when I pulled outta the airport at Denver the night I picked up my '01 and was blinded.. I don't see why they need them on the rearview mirror as the rear window is dark enuff w/o it...

 

What's funny is that every car BUT an X or Superduty needs the dimmer. The X sits so high and the back glass is dark enough that the auto-dimmer is only slightly beneficial. I still like it though, if only for the geek factor. The mirror is manufactured by Donnelly Corporation which was recently merged with Magna which is a high-end, high-tech automotive supplier. They make some cool stuff. I bought one of their mirrors for my Expedition back in 2000 when auto-dimming with embedded temp and compass was cool.

If only they made Ford towing mirriors.

 

I have the same dimmer switch as well. Loved it but got something better now . 6inch procomp lift. lol

 

So what is the other light for? I have the auto-dim rear view and the button on the bottom will activate/deactivate the green light on the rightside of the mirror, but there is also a left side LED - what is it for?
I honestly cannot tell the difference with the auto-dim on or off.

 

I have it on my X but always thought it stupid with the window tint. I have never had to use it since I have been driving it.

 

the thing on the left should be the light sensor for the mirror, look closer and your should be able to see the small circuit board behind it

 

you are ALL wrong....

the little green light is so the driver can tel which window to look out of !!!
indicates front of vehicle

 

You too are wrong. When the driver gets bored at the stop light, he pushes the button and sees a green light which means he gets to go.

 

DANG !!!!

Knew it was one or the other - I like your function betta !

and don't ya know this thread made me look at it last night and noticed it was off
