This idea started after using Haze weather which also modifies some light records in a similar(ish) way. I didn't notice the light option of that mod till some days ago, but when I tried I become ADDICTED to the higher values of amplitude and period of flickering light. 

The effect changes with different ENB presets as I notices after changing one ENB, most of the light changes I had done was not visible anymore or became disturbing (too much strobe effect) so this mod might work less well with some enbs, I will add a list of all the ENB tested and working well.

This is because the perceived effect changes a lot with different ambient and point lights values, higher ambient light values require higher amplitude changes to be noticed, and lower ambient light values requires lower amplitude changes or they become annoying strobes.
Anyway I didn't put any enb preset in required mods because the mod might work well even with most ENB with not so different from average of ambient light and point light ratio.

This mod was born while I was using ELFX shadow and all it's requirements, plus I extended the modifications to an optional ELFX exterior.  I will probably extend my mofications to LUX suite (DONE), Skryim is Luminous, Relight Skyrim, Window shadows RT, Lanterns of skyrim II once I will re-install them (I like to change lighting mods). 

Total open permission, or I should say, I even invite you to use this idea to make your own mods to adapt this to other ENB and/or lighting mods yourself and save me time to make them myself, I will be grateful, just not for paywalled mods.

ENBs tested with ELFX

• AMON Reborn for Obsidian weather 
• Amon Reborn NAT
• NAT.ENB III 
• IIENB
• Soul Spectrum ENB for Cathedral Weathers (differently from author preference, I suggest to use ELFX enhancer for clearer dancing light effect or you can just lower the enb ambient light)
• Azurite Horizon ENB
  

For all Picho ENBs I tried, I noticed that in order to get the bigger effect I intended, you need to check ENVIRONMENT -> ignoreWeatherSystemInterior, and lower interior ambient and direct lights and increase interior point light, better to lower also night ambient light (of exterior)

• Pi-cho for Obsidian Weather re 
• Pi-cho for Cathedral Weather b2
  

UPDATE now you can grab the Pi-cho tuned beta version! Anyway you might anyway prefer the "normal" ELFX version if you like a more subtle effect/less strong effect.

With these following ENBs I used ELFX even if authors suggest only LUX

• Bjorn ENB-Reshare  also the dark age reshade option  
• Pandora ENB with Haze weather 
• Mara and Dibella
  

LUX versions each have its own tuned files in the downloads tab

• Picta Realis  
• ENB of the Elders 
• Pi-cho - Azurite Weather 8.5b2 
• NAT.ENB III
• Kauz (seems good with NAT III version, but I didn't test it very deeply)
• Bjorn ENB-Reshare  (use azurite lux version or NAT III version)
• Azurite Horizon 
• IIENB (same version as Azurite Horizon)
  

You can also use Community shaders, it works also with them (tested with ELFX version)

Installation

• Be sure the ESP (that is flagged as ESL) loads after LUX or ELFX shadow and other mods modifying lights (such as embers and NAT)
  

Known issue: still I didn't identify why equipped torches are not affected by flickering


Special Thanks to:
too many modders to name them, so I have to thank all modders making Skyrim the best game possible, because it's a bit like LEGO: you can build it yourself and play.
Of course, in relation to this mod, main thanks go to the authors of ELFX and LUX, and all the authors of those great ENB presets and weathers I used, and of course to the author of ENB itself. Thanks also to CS for offering a nice alternative too.
