I've seen the same thing on Southwest 737s approaching Dallas Love...but
not all of them?

Around here, perhaps it helps separate Love traffic from DFW traffic
when the airspace starts to get tight?

I'm curious to hear an explanation too...

And while we're on the subject of landing lights:  I very often see
airliners approaching DFW with varying combinations of their landing
lights on or off.  Is this to help the control tower get a visual on a
specific aircraft?  Or is it simply burned out landing lights on these
