Long and short tester screwdriver

• It is a test screwdriver used to detect electrical current in an electrical outlet or extension cord.
• When the screwdriver's metal tongue is inserted into one of the socket's connectors or touched a wire, and one of the fingers of the hand is placed on the back of the screwdriver, the light bulb shines, indicating the presence of an electric current. If it does not shine, this means that there is no electric current.
