Custom Light Source Crashes Game

Basically I have the custom model attached below.
It imports properly into the editor, however whenever I select the model to be used as a unit/doodad/whatever the editor proceeds to hang.

My immediate reaction is "it has no sequences". Add a single Stand sequence and see if that works.

Well, that prevented it from crashing on selection.
However it now crashes on placement.

do you have anything to select? any model?

nope, its just a light source.

Anyway I managed to get a functional light model to work in the editor.
The problem now is that regardless of what colour and stats i set, it still appears as a plain light in the editor.

Ive atached the new model below.
