Mark Ferradini, I tried your edits and the light did not disappear after the gear went up.  When I switched things back, it did.

I'm still tweaking.  I think the first four entries probably need to go since wing flex leaves them unattached to anything.  I am also wondering if the cockpit lighting is bright enough.  Finally, anyone want to take a stab at the scattered light on the underside of the fuselage?

The 727, with two landing lights on the wing root and two more on the wing, is made for Shockwave 3D lights.
