An electrical testing device has an electrically insulating housing with one projecting electrode and another insulated wire containing a second projecting electrode. A neon tube is included within the housing and gives a visual indication of voltage. The exposed electrodes are generally spade-shaped to permit introducing the same into the slots of a conventional receptacle to determine if the receptacle electrodes are live. In addition, the testing device also has an auxiliary electrode within a slotted portion of the housing.
