FAQ:

Q: What is a self powered test light?

A: The self-powered test light is similar in design to the 12 volt test light, but contains a 1.5 volt penlight battery in the handle . It is most often used in place of a multimeter to check for open or short circuits when power is isolated from the circuit (continuity test).

Q: What is a test light?

A: A test light, test lamp, voltage tester, or mains tester is a piece of electronic test equipment used to determine the presence of electricity in a piece of equipment under test. A test light is simpler and less costly than a measuring instrument such as a multimeter, and often suffices for checking for the presence of voltage on a conductor.

Q: What is automotive test light?

A: A test light, sometimes called a test lamp or voltage tester, is a simple but extremely useful electronic tool to check your car’s circuits—that is, the presence or absence of electricity to a certain component or piece of equipment.
