I have a '12 coupe. The bottom of the rearview mirror has 3 buttons for garage door openers. To the right of these buttons is a red light that - just barely noticeably - shines down toward the gearshift lever. Anyone know what this is?

 

i've seen that in amber in E series as well which serves simply as a dim reading lamp

 

Yeah, if its what im thinking (centre of the mirror) its just to lightly illuminate the cabin.

if its a really small light, that might be for setting up the garage remote, as confirmation of learning/ using it.

 

...thinking that it's just soft enough not to ruin one's night vision, yet assist in finding something in the dark

 

isn't this just the MB "ambient lighting"?

Off topic, I love both of your cars mate!! The multispokes on the E63 is sweet, and your ML63 is wicked, I love that gen more than the new gen.

 

Thanks mate! I miss the E63. Was a great all rounder that car.

I will post some pics up of it later.

I love the C63 with those multispokes (like yours). One of the nicest designed wheels from Benz. I still have stock 18's on mine, but when the rubber runs out, i will most probably get a set of the multispoke 19s for the C63 too.

 

There's another little bulb just to the LEFT of the garage door buttons. That's the one for confirming the remote setup.

The red (or perhaps amber) one is to the RIGHT of the 3 door-remote buttons. It could be for night-time ambient lighting, but the dash gives off way more light than this thing does.

 

it's ambient/mood lighting. it's not for reading or anything.
