They might not be used?

As I understand, the bi-xenon lights use the same lamp for both low
beam and high beam. There's a shutter mechanism being switched when
you move the stalk so that actually the xenon light gets reflected by
a differently shaped reflector in the back of the housing for high
beam, throwing a larger and different pattern.

The light casings you see might as well be for the non bi-xenon high
beams. They would light up when low beam is switched off and high beam
is switched on in a non xenon equipped car.

In your car they might just not be operating, but it's cheaper to use
the same assembly.
