Gardner Bender Non-Contact 12 VAC to 600 VAC Light Bulb & Fuse Tester

Holiday light bulb and fuse tester. Engineered with a bulb pulling tool on the end to assist in removing bulb from string light sets, and a simple push-in-to-test bulb tester on the back. Tests both LED (light emitting diode) and incandescent string light bulbs. By flipping a switch, the tool becomes a fuse tester making troubleshooting a blown fuse quick and easy. Can also be used as an adjustable sensitivity non-contact voltage tester to test for the presence of AC (alternating current) voltage prior to working on any electrical project. Detects voltage from 12 VAC to 600 VAC. Non-contact feature means never risk touching live wires in order to determine the presence of voltage. Provides both a 360-degree bright red light and an audible beeping indication of the presence of voltage. Includes comfortable rubber over-molding slip resistant grip. Requires (2) LR44 button cell batteries, included.
