-ambulist means someone walking around, not someone using a flashlight. somnia (sleeping), + ambulist = somnambulist, sleep walker.

There is no single word that means to read by flashlight.

Reading whilst walking would be Lectioambulism I suppose. Or perhaps Ambulolection? Or maybe Ambulacrosis if reading out aloud.
