Probably not what you want to hear but you could write that yourself (in case you don't figure it out with the system as-is).
I'd ignore all A8 light properties/ members/ functions then and code it from the ground up (picking different names has the advantage that you save CPU resources and not have your stuff overwritten by acknex).
A light struct (position, color, range, on/ off), then a loop over all lights which does camera frustum per frame. There you set analog array data to be used in the shader (such as vecMyLightPos[8], ...).
Create a custom light.fx to be included in your shaders for light calculations or change the functions in code/default.fx which reference vecLightPos and similar.
