What's this 2?

[The-Acre]

I've got another what's this.  Under the rear parcel shelf brake light is a dark plastic piece.  I noticed there's a small camera lens inside, anyone know what it does?

might be a light sensor to dim the mirrors at night if a car is behind you. But must admit I've not noticed it before so going to have a look now

For the reversing camera?

The reversing camera is just above the number plate. I only noticed this one when the sun was on it, look exactly like the reversing camera lens though.

I thought there were two, the one above the number plate and the one by the high level brake light.

Not sure, I know the later reversing camera is different.  Maybe the government have hidden it to keep watch on us!!....or maybe the Russians!😁

Is it 100% a lense? Could it be a bung of sorts to hide a screw access hole or something? Cant think of any reason for another lense, except a po having stalled a rear dash cam...

mine has one too. I assumed it to be a light sensor .

Definitely a lens. When the sun was on it it looked just like the lens from a phone camera.

It is an ambient light sensor to control the instrument cluster lighting.

Brilliant site this! Virtually everything gets an answer. Tonight I've learned about the ambient light sensor and also what to do about TPMS problems. Thank you all.
