I was checking around at airports and noticed that some don't have the green centerline lights on the taxiways. Des Moines International was the first location. The yellow taxi lines are visibible but no lights. KMCI is a little bit bigger than KDSM and has the green lights. Shouldn't all airports have these lights?

Some airfields have the taxiway center lights and some don't. You can fix that yourself with ADE if you like.
