I have noticed that the underseat light on the 350i has been moved more sensibly to the left side of the seat bucket so it doesn't shine into your face in the dark. It also uses a nifty infrared transmitter/receiver reflecting off the seat latch and logic switch to turn it on and off accordingly. This means no more 'MET-IN' light and closing your seat twice just to make sure. However as a light source it is still weak and the sensor is always on, so there is a risk of battery drain.
