Those are the cornering lamps. They both come on when you put the car in reverse and the headlamps are on. Otherwise, they come on individually when you're going below 25 MPH and you use the turn signal or when you turn the steering wheel at low speed.

They illuminate the edges of the road in the direction you are turning.
