While I really appreciate your explanation, with all due respect, I believe what you were saying about "Alternative" is kinda playing with words. Also, we both know disabling the DL through P3D doesn't solve the problem as there's no illumination on ground anymore but for PMDG products not the default simobjects. So I'm not sure why you've mentioned me that there's a button which doesn't solve the problem. I hope I could interpret my concern properly. To wrap it up, that would be much much much appreciated if PMDG could provide a button, an alternate, an option, or whatever you call it to revise the lights so they could work properly with DL off.
Cheers.
