Like I mentioned [in this thread](https://groups.google.com/d/msg/cesium-dev/fXmyCEkCP9k/cUICKtptCgAJ), Threejs integration with Cesium is still largely experimental. Since it’s essentially rendering the scenes separately and combining them, you should be able to add lights to your Threejs scene and it’ll work (but it’ll only affect Threejs objects). I think the tricky part is placing the light at the right location. This PR might be doing some work on that:
