How to make the billiboard light not to be buggy?

[clock123]

Move them around a little, reduce size etc. If you want them to be a real master piece you've got to spend like minimum 1 hour on them, but that is for a real master piece.

thanks for the advice
is there anyway i can copy "stuff" ( items, billboards.. ) from another custom story to mine? , i want to copy these billboard lights in one story, into mine. is there a way to do it?
