Hi there.
It's the diode for your alarm system

Well you got the "clown nose" for it.
Might be your rear view mirror has been exchanged for some reason

Wondering if there's some way I could check if the alarm is actually fitted but not coded ..

I don't have an alarm either, but have the same mirror.

Welcome to 1999.

It's the old fashioned anti-glare button. Have you tried twisting the button at bottom of the mirror either way gently? It tilts the mirror slightly to avoid glare from headlights behind.

LED, actually, but as that stands for Light Emitting Diode you're close.

You mean you didn't know you have an alarm. That's not unusual, since you don't have to do anything to activate it other than to lock the car. How it works is in your manual.

But you do; just because it might not "beep" or "honk" when you lock it, it still activates.
