Patching mods you use is very simple, and shouldnt take you more than 5 minutes (I literally made this mod in about 3.5)

The wheel has already been invented, you just need to use it. If editing a non NV scope, you literally just drag and drop the enchantment.

In total you will be:

Deleting one keyword, adding one enchantment, and changing one Zoom.  (NV -> Dynamic NV)
-or-
Adding one enchantment. (Normal Scopes)

Delete: dn_HasScope_NightVision [KYWD:00163054] 
Add: CSM OBJF NV  "Night Vision" [ENCH:XX04D800]
Change: ZM_Standard_Scope_x#_NightVision [ZOOM: 00XXXXXX] to ZM_Standard_Scope_x# [ZOOM: 00XXXXXX]

Viola! The lights are now off when bright, and on at night!
