First generation IH885xl interior light on/off question?

Quick question as just trying to diagnose a suspected drain on the battery which position is the off position on the interior light. The interior light has never worked on the tractor and was never fixed as it's something that was never needed however I've been recently having battery issues after another operator was using the tractor and I can't help but think he changed the position of the light and I'm damned if I can remember what position it used to be in. Simple problem I know but it's these sorta Q's that google struggles with :P
