Searching for dynamic lights in game

So let me preface this question with the actual thing that I want to accomplish. In our game, when a certain character runs through the interior, we would like for the dynamic lights within a certain proximity of this character to turn off.

Now, this would involve searching through the mission editor, testing each dynamic light object whether it's certain position lies within a certain "bubble" around this character and then calling a "turn off" on those object id's.

Any suggestions?
