How is a circuit-powered test light used?

First make sure the test light is rated for the voltage you are working on. Don't use an automotive 12v test light in your home wiring. A simple test light has a test lead and a ground clip. You attach the ground clip to a known ground point (a bolt on the chassis of a car, or the - battery terminal). You then simple touch the test lead to the area being tested. If the light illuminates, then there is power there, if not, then there is not power there.
