I'm not familiar with the type but they might actually be "recognition lights" rather than "landing lights".
Similar idea though, basically white lights with similar intensity to landing lights. Our SOP is for "recy lights" (as we call them) on below FL100. We also use them to "flash" oncoming traffic in the cruise, a bit like flashing your car headlights when you see a mate.
I've not flown in that region but by all accounts the more lights on the better. It's not uncommon to see aircraft recognition lights from 70+ miles away!
