9000 CS model: Additional backup lights in front indicator lights??

I'm puzzled by the following: In the dutch SAABforum there is somebody offering 9000 CS model front indicators (the orange ones, so before

1995) that have on the corners an additional white section, that lights up with the backup lights, so when the car is put in reverse.

So these woud be Front backup lights. This option has never been sold in the Netherlands so it seems, and frankly I never heard of it.

For a photo see:

Does anyone know in which markets this option was sold? What is the proper name for this option, in English and/or swedish?

It seems lots of cars *not* fitted with this option do have the required wiring lying idle in the front fender, so people could easyly fit this option... ONce they can get a hold of these special indicators

Thx, NF
