Rain sensor

[tucpal]

well technically its an infrared radar camera that picks up the oncoming lights from an oncoming car and tail lights from behind etc
and street lights etc to turn the high beam on and off they call it a HBA camera
so if you want HBA this is the one you want but this was only an option with AFL

this is the opel eye camera traffic sign recognition and lane departure camera adaptive cruise control collision alert.

what i would be interested in is side blind spot alert system
how does that work is it just the sensor in the driver's mirror glass that detects the blind spot
or is it just the side facing parking sensors
