N Scale Lighted Track Tester – For DC & DCC Trains | Check Rail Power, Shorts & Direction

This compact N scale lighted track tester is a must-have tool for diagnosing your layout’s electrical health. Designed in-house by N Scale Workshop, this tester slides easily along your rails and gives instant visual feedback on power presence, direction, and shorts—whether you're running DC or DCC.

🔴🟢 The LED changes color depending on polarity: red for one direction, green for the other. This makes it perfect for checking which way your trains will run—or identifying issues like reverse loops, poor solder joints, or dead spots on the fly.

The body is 3D-printed in durable, unpainted PLA for a lightweight, reliable finish. Small enough to keep in your pocket or toolkit, it’s ideal for quick troubleshooting during layout builds, rewiring, or regular maintenance.

📸 Check the listing photos to see it in action on one of our personal layouts.
