External mirrors triangle

On the corners of both of the drivers external mirrors there is a small triangle.
Thought first it was blind spot monitoring, but don't think that’s available on the G20 in the UK.
Then it was auto dimming. No, that’s drivers side only controlled by the rear view mirror.
So what is the triangle for? Any ideas?
