Test Light

A test light is a simple electrical testing tool used to determine the presence of electrical voltage in a circuit. It typically consists of a handle with a bulb or LED at one end and a probe at the other end. The probe is used to make contact with the circuit being tested.

When the probe of the test light is touched to a live wire or terminal, the bulb or LED will light up, indicating the presence of voltage. This can be useful for troubleshooting electrical issues, such as identifying if a wire is live or if a fuse is blown.

Test lights are commonly used by electricians, automotive technicians, and DIY enthusiasts for basic electrical testing. They are portable, easy to use, and provide a quick and convenient way to check for voltage.

In the supply class Electrical And Electronic Properties Measuring And Testing Instruments, test lights are categorized as a tool for measuring and testing electrical properties. They are part of the larger group of Instruments And Laboratory Equipment, which includes various instruments used for scientific research, experimentation, and measurement in laboratories and other settings.
