Auto light on function
 

Hi all! My x does not have auto light on function but have rain sensor function, so may I just put this part on to replace my existing one to have auto light on function on my x?

It's NOT as simple as just replacing the switch. You'll need a new lighting module and a light sensor to make that function work. Although, housed in the same area, the rain sensor does NOT equal light sensor.
