Kai, It is not the case for me that, once having installed the CS777 Version 1.4 into P3D v2 using the Estonia Migration Tool, certain exterior lights work when running P3D v2 in legacy mode. The lights in question are the wing lights (nav, wing and strobe) and the tail lights. Moreover, the beacon lights do work but are extremely faint. Although this does not detract from what appears to be most people's experience of a greatly improved and enjoyable virtual flying experience with the 1.4 update, I would be grateful if you kindly confirm that all such lights are working in your simulation and whether any special tweaks were required to achieve this. I have read on the L1011 forum that special measures were required to get similar lights working with the L1011 on P3D, e.g. reloading the vehicle ( I have tried this with the CS777 to no avail). Your comments would  be most welcome here, please.

Update to the above. I have just installed CS777 1.4 on a Windows 8.1 machine in
P3D v2 and the lights work correctly. I am now debugging my Windows 7 installation of P3D v2 to determine why the issues with lights persist there.
