How will the incoming patch that limits the number of light sources to 8 affect this addon?
I suspect Orbiter will handle that internally. It will have to I think, because vessels don't know about the light sources registered by other vessels. In this case I wonder if Orbiter will limit the rendering to the maximum limit, or whether it will prevent more then eight sources from being active concurrently (LightEmitter::Acitvate returning false if the source cannot be activated at the time due to the limit). For the former, I won't have to do anything.
Keep in mind this hackish add-on was just made to sample the multilight feature with vessels other then the stock ones. I will wait until this feature is more tested before updating the orbSpotlight add-on to use this instead.
