THE HOUSING INCLUDES AN INTERFACE FOR MECHANICALLY MOUNTING AN ELECTRICAL POWER SOURCE TO THE HOUSING WHICH ENERGIZES A LIGHT SOURCE IN THE HOUSING. A PRESSURE-SENSITIVE SWITCH IS DISPOSED ADJACENT THE SIGHT APERTURE FOR ACTUATION BY A FINGER HOLDING THE HOUSING. THE POWER SOURCE IS LOCATED ON THE SIDE OF THE HOLDING THUMN GENERALLY OPPOSITE THE REMAINING FINGERS OF THE HOLDING HAND TO PREVENT THE POWER SOURCE FROM INTERFERING WITH THE USE OF THE REMAINING FINGERS FOR MANIPULATION OFD THE ORGAN. THE POWER SOURCE IS SELECTED FROM CONVENTIONAL BATTERIES, RECHARGEABLE BATTERIES, AND HOUSEHOLD CURRENT DRAWING TRANSFORMERS. TERMINALS ELECTRICALLY CONNECTING THE LIGHT SOURCE WITH THE POWER SOURCE ARE CONSTRUCTED TO SIMULTANEOUSLY RELEASABLY SECURE THE LATTER TO THE HOUSING.
