J 35616-200  Test Light - Probe Kit

CAUTION: Refer to Test Probe Caution .

A test lamp can simply and quickly test a low impedance circuit for voltage. A DMM should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present.

The J 35616-200  is Micro-Pack compatible and comprised of a 12-volt light bulb with an attached pair of leads.
