I love dark games
I checked out the scripts, and they work as intended with just a few adjustments. First, which version are you using. I'm V1.20_1.14 (no mods) If your using one of the newer mods it may not work? (haven't tested it yet)
Did you follow the instructions carefully? (Important with naming the entities correctly)
Also, open the scripts and change all "timers" from timerstart/timergreater to etmerstart/etimergreater!
Lastly, I placed my "dynamic" light outside the playable area
of the bldg. Is yours an indoor setting or outside?
Edit: just tested with S4real's Z-mod and works just fine.
One thing I did notice you have to set the "dynamic" light
to a radius of "1" or more, not zero. It doesn't work
right when set to zero for some reason.

My games never have bugs. They just develop random features..
