Pretty close. For the dataref, you do not need to init the dataref with the same values as the light – rather in your XPLMGetDatavf callback, you need to simply change the values that you wish to change and leave the rest alone.

See here.

It’s the same idea for custom spills and custom billboards – dataref gets a chance to change all, some, or none of the 9 params.

And…XYZ is _not_ part of the 9 params. If you want to change the XYZ, just use animation. You don’t even need the full custom lgiht for this!

Create a light, say, in ac3d. Edit light type to LIGHT_SPILL_CUSTOM and add the parameters and dataref in a text editor. I suppose the plugin must initialize the dataref with the same values, then rewriting any parameter, the x-position, for example, would move the light?
