What is the light call between driver door and rear on both sides of car a Chevy carprice ls brougham 87-89?

That's the B-pillar. The B-pillar is the structural pillar between the front and rear doors of a car. There isn't a specific, single name for the light *on* that pillar in a 1987-89 Chevy Caprice LS Brougham (or any car for that matter), as that depends on the model's specific features and whether it has any additional lighting there beyond the main interior lights.
