Lightweight, portable, battery operated LED units, probably to be found in such places as RadioShack, ought to do the trick. Some of these units can be clipped to the collar, or on the bill or brim of a hat/cap, attached to a fishpole just out of lens, etc. and focused on one side or profile of the face or the other.
I would be careful about placement below the chin area, unless you actually want one of those Freddie Kreuger fright light looks for a horror flick – remember holding a flashlight under your chin and shining it upwards? Boo!
