5-90V DC Wide Testing Range Test Lights- The automotive circuit tester light with 5-90V DC voltage testing range, widely and ideal for checking various vehicles, electrical circuits, automotive headlights, taillights, turn signal circuits, faulty sockets, fuse connections, also for testing other 5-90v DC wirings and circuits.Accurate & Easy LED reading display - The LED display of Test Light is easy to read.Showing the voltage helps diagnostics quite a bit.The red and green lights let you know if you are on the positive side or negative side. Red light of the automotive circuit tester light indicates positive polarity and green light indicates negative polarity.buyirectional voltage testing tester pen - This upgrade circuit test light is a buyirectional voltage tester. You can attach the alligator clamp either to negative or positive ground, there is also a light emitting diode on the circuit board for polarity indication, red light indicates positive polarity and green light indicates negative polarity.Handy Probe & Flexible Extended Spring Wire - volt meter probe is very handy for checking voltages of batteries or low voltage circuits. It’s great for seeing how many volts a Liion battery is running on, to know its charge status. This probe also is good for checking continuity as well. Spring wire can be freely stretched up to 96 inches, with a wide measuring area; Anti-bending design of the tail wire, needless to worry about bad contact of the line.Widely Use of Automotive Test Lights - The automotive circuit tester light designed to test 5-90V DC voltage.Works on all 5-90v vehicle electrical systerms: Cars Trucks Golf Carts Motorcycles Boats etc. Can be used to detect power, ground and find shorts and breaks in the wires. Quickly check automotive headlights, turning signal circuits, taillights, socket failures, fuses, connections, disconnection, etc. Product Description Test Light Automotive, Automotive Circuit Tester DC 5V-90V DigitalTest Light Voltage Tester Test Pen Auto buyirectional Voltage Tester Electric Test Pen for Cars Truck Live Wires Golf Cart Fuse Digital display of Automotive Test Lights for accurate voltage readouts. 5 -90V tester for DC 5/12/24/36/48/60V/72V/84V system.
