10PC Bulb for Car Circuit DC Tester 6-24V Voltage Gauge Test Light Measuring Pen

Product Description

This professional automotive circuit tester is a must-have tool for every mechanic, DIYer, and car owner. It is designed to quickly and safely check DC 6V, 12V, and 24V electrical systems on cars, trucks, motorcycles, ATVs, boats, and small engines.


Equipped with a high-brightness LED indicator, the tester lights up clearly when power is detected, allowing you to easily verify live wires, ground points, fuses, bulbs, and connections—even in dark engine compartments or under the vehicle.


The sharp, durable metal probe easily pierces wire insulation without damage, helping you locate shorts, broken wires, and bad contacts fast. The long, flexible spring cable extends up to 1.8m, providing enough length for testing hard-to-reach areas like under the dashboard or chassis.


Features an ergonomic insulated handle for safe and comfortable grip during extended use. No batteries required—simple and reliable direct circuit testing.


Common Uses:

  • Test battery voltage & charging system
  • Check fuses, relays, and light sockets (headlights, taillights, turn signals)
  • Locate short circuits, broken wires, and poor connections
  • Verify power and ground in any automotive DC circuit
Lightweight, compact, and built to last, this test pen is perfect for both professional workshops and emergency roadside repairs. Keep one in your toolbox and avoid expensive shop bills!
