tes3cmd is a command line tool for batch operations on Morrowind (TES3) plugins.

It currently lives http://code.google.com/p/mlox/wiki/Tes3cmd, where you can find instructions for download/install/usage and so on.

A new version is coming soon with bugfixes and new features.

tes3cmd allows you to do various things, like:

• Clean plugins (probably one of the most useful features for regular users)
  
• Generate a "multipatch" for leveled lists and more
  
• Convert a plugin or savegame to readable text (handy for understanding plugins)
  
• Global search and replace
  
• Global modification of records via small scripts written in Perl
  
• Much, much more

Out of curiosity, what does not work changing directly light_dwrv_neon00 values from the Light tab in CS?

Dwemer blinking lights is not 100% compatible with light mods but instead of making patches I wanna make bat files to change values in "Dwemer blinking lights.esp".
