Did an Ecuadorian market truck get us spec lights or is it lucky enough to get lights like the Brazilian Arteb version?

I would like to know, too.
From what I've read, I believe GM Brazil and GM Argentina served much of South America but I'm not sure their their GMT400 was sold in as many markets; GM North America may have had a toe in, e.g., Mexico. IIRC, Mexico and markets south of Mexico were served by a mish-mash of GM production over different years and vehicle models, with some parts / vehicles coming from GM North America, GM Mexico, GM Argentina and GM Brazil (and maybe others).
@MrPink may have some remarks to add.
Interesting reading, here:

"The main market for exports was Mexico, followed by Argentina, Venezuela, South Africa and other Latin American countries."
