I notice, on the passenger side to the rear view mirror, a large bulge with what appears to be several sensors. They look like LEDs, literally. I am presuming, this is is either light sensor or something similar?
Now, I know 100% that is not dimming mirror sensor, that one is in the mirror itself.
What is it for then?
Very pragmatic question, as I have stripped model without rain sensing wipers or automatic high beams. But, if say it is for Auto high beams , maybe I can add it. I like that feature on wife's RX350.
Yes, read manual, no mentioning of what it is.

It's rain sensing sensor. Google all mighty.
Auto high beam camera is in the mirror. Lower bottom part of it, center.
