For professional use only:- Until now, the industry advice has been "Never use a test lamp on 5V sensors" because standard 12V incandescent test lamps pull too much current and can instantly destroy a delicate ECU driver channel or more likely will just short the circuit to ground. This custom-engineered 5V Reference Test Lamp bridges that gap perfectly. It allows you to safely place a dynamic load on 5V reference lines, VREF networks, and sensor supply circuits to instantly verify wiring integrity. This will put an 80mA draw on the circuit which is safe and within most circuit tolerances, This test lamp unit has 1x female banana and 1x male banana and includes 1x fine back probe
