The NLG knocking noise heard on taxi-in to stand, what could cause this knocking noise?

That's a pilot taxiing perfectly on the centerline, which makes one of the two nose landing gear tires hit all the taxiway centerline lights.

Just like the sound the tires of a car make when they hit the cat's eyes on a road at speed.
