Ok, here is a test version of the Hospital Ship with lights:

It's a bit tricky because the lights are on in daytime too, so they can't be too bright. But I think it's a pretty good compromise now. I would also like to add more lights, but it seems that the number of them is limited in one 3d model. They also can increase computer usage. I wonder if it should be used in other imported ships too... maybe passanger liners.
So test it if you have time, this requires OH II to work (oh, in the museum daytime view it's nothing too special, night makes it shine!

).
