Horizon Tool 81 Logic Light Circuit Tester for 6V 12V 24V DC Systems

The Horizon Tool 81 Logic Light Circuit Tester is a self-powered diagnostic tool designed for testing live and non-live 6V, 12V, and 24V DC electrical systems in automotive, marine, and powersports applications. This innovative circuit tester eliminates guesswork by clearly indicating both power and ground conditions, making electrical troubleshooting faster and more accurate.

Key Features:

• Patented LED edge-lighting illuminates the handle red when power is detected and green when grounded
• Self-powered internal source allows testing of both live and non-live DC circuits
• Works with 6V, 12V, and 24V DC electrical systems
• Creates less current draw than traditional incandescent test lights, protecting sensitive electronics
• Quickly confirms proper grounding to save diagnostic time
• Tests for poor grounding, broken wires, and blown fuses

The color-coded LED system makes it simple to distinguish between power and ground at a glance, reducing errors and speeding up electrical system diagnosis. The low-draw LED design is safer for modern vehicle electronics compared to traditional high-current test lights with incandescent bulbs.
