P.S.: here is your file back. I have installed a second version of your XPresso idea. The two nodes “Math:Subtract” and “Universal:Integer” could be replaced with a Formula node “mod($1;1)”, but the Range Mapper has a Modulo function already build in. So I reduced the processing “tree”.
I have also placed two “User Data Slider” to the XPresso Tag. I placed them to the “Tag”, as you can now save the Tag as tag preset. Object Manager>File>Save Tag Preset…
This allows to select any light object and use the Object Manager>File>Load Tag Preset… to the light. (The Light node in the XPresso is set to Attribute Manager>Node>Reference Mode:“Relative Reference” to make that happen.
I placed it as HUD in the Editor window, but that is just an option, not mandatory for its functionality.
