2Way Audible Premium Automotive Circuit Tester Test Light with Extended PU Spring Wire Car Light Tester with Stainless Probe and RedBlue Indicator Emitting Diode for Testing PositiveGround

Jastind professional automotive Circuit 6-24V DC 2-way Tester designed for car electrical circuits, automotive battery, battery charging systems, ignition systems, which is a must have tool for any automotive engineer, electronic engineer or circuits DIY. 1. 6-24v Professional Circuit Tester/circuit test light, designed to check car vehicles electrical circuits and other DC 6-24v wiring and circuits, ideal tool for automotive circuits trouble shooting. 2. 2 Way Circuit Testing, ideal for testing positive also for ground, usually hook the clamp to the ground and connect the probe to the positive terminal, and conversely(clamp to the ground while probe to the positive) it also works and tests well. 3. Audible and Polarity Indicator Emitting Diode, when testing, there will be successive audible sound to indicate there is voltage in the circuits. Also it indicates circuits' positive or negative polarity, the LED light indicates red for positive and blue for ground. 4. Portable Extending Spring Wire, equipped with high quality 98 inch long enough PU coated spring wire for easy extending operation. 5. Constructed with high quality acetate fiber body, high toughness and shatter-proof than normal plastic. Also with a sharp stainless steel probe for piercing and hard to reach areas. Please Note This is a DC 6-24V circuit voltage tester, don't use this product to test any AC system circuits or equipment, and don't use this to test circuits which voltage beyond 6-24v.
