I have had the PMDG 737-600,700,800,and 900 for a while now and always wondered about this but never asked, so now I am asking about it.Whenever I switch on the runway turn off light switch I never see any lights come on outside of the plane. Is this just a dummy switch or does this switch really turn on some lights? Where are these lights located?Joseph Feleppa

I think they are just for show...

Joseph,The runway turn-off lights swithches are not simulated. The actual lights are though. When you turn on the taxi light you also turn on the turn-off lights. The turn-off lights are located at the wing root where the fixed landing lights are located as well. The taxi light is basically just the light on the front gear strut.Hope it helps,
