Sequencing an emissive material along blueprint instances

Oh I missed the first BP screenshot from before, now I see it!
Now I am able to properly analyze and hope to learn from this.

So the BP within the object itself I get, even though I can’t connect the “Next Light” node to the last “target” slot

](filedata/fetch?id=1856566&d=1611673101)

So that by itself already creates a sequence effect, and it can run independently right?

So the 2nd method you showed from the level BP, is to create a similar sequence but from an outside BP right?
Cause over there I am not able to get the target node for the “sequence numbers”

](filedata/fetch?id=1856557&d=1611670447)
Any option I choose doesn’t give me the same node as the one you have in the screenshot.

I feel I am making a mess of something that should have been fairly simple…is that me? haha

Would it be possible to fire them manually? maybe I’d be better off this way, so I can also control the emission power to fade in and out.

Thanks again
