- Wide Application: This circuit test light is designed for 6-48V DC voltage, making it perfect for diagnosing electrical issues in cars, motorcycles, and lawn mowers. Quickly check headlights, taillights, and turn signal circuits with ease. - Reliable PCB Display: The high-visibility digital display shows circuit signals and fluctuates according to measured voltage, providing a clear visual indication of your electrical system's status. - Unidirectional Voltmeter Display: Connect the clip to either the negative or positive ground while using the probe on the opposite side. The LED indicator will glow red or green based on the circuit condition, while the voltmeter offers readings in one direction only. - Quality Manufacturing: Equipped with a durable stainless steel probe for easy wire piercing, this test light is effective in tight spaces. The insulated rubber head safeguards against electric shock, ensuring safe handling. The PU spring wire is heat-insulated and oil-resistant, making it reliable for various conditions. Use Scenarios: 1. Quickly diagnose why a car's headlights are not functioning, ensuring you can resolve issues before hitting the road. 2. Test the turn signal circuit on a motorcycle to guarantee visibility and safety during rides. 3. Check the electrical connections on lawn mowers, helping you maintain their performance and extend their lifespan. This circuit test light combines functionality and durability, making it an essential tool for anyone working with automotive or garden electrical systems.
