You can't see them because the plane is flying away from you.

You're looking at the plane from the back, hence you don't see the landing lights.
EMBQA and Scorpio are right. It says in the remarks the other plane has just taken off from rwy 15, and the one in the front is landing on 27, which means that the landing plane has to approach from the left hand side of the rwy 15 direction (which it currently does). If we'd be looking at it head-on, it would have to approach rwy 09, which is unlikely because it says otherwise in the remarks, and because it would have had to cross an active runway with a plane rolling for take-off on it.
So the reason you're not seeing any landing lights is indeed because you're looking at a plane flying away from the camera position.
