So I have 17 cruze I was wondering if I could put on the mirrors that have blinkers and also with the blind spot light on my cruze if mine doesnt have those mirrors?

 

never hurts to ask the dealership about accessory add on's.
blind spot monitoring probably can't be added as it requires sensors and modules that must be built as part of the computer network. Even if you could buy it...its probably $4000 in parts.

the turn signal indicators in the mirrors, it might be a easy dealer add on.
