  • 2-in-1 Trailer Adapter: It's both an adapter and a tester! Easily convert your connector from 7 pin to 4 pin, you can also use it to test trailer lights before towing.
  • 6 LED Indicators: Swiftly verify taillights, brakes, reverse, turn signals, electric brake, and 12V power. Each feature has an LED for rapid, precise trailer light testing. E.g., right turn signal triggers the respective LED; for incorrect wiring or no triggers, there will be no light.
  • Premium Materials: Robust ABS construction shields against rust; Brass connector provides excellent conductivity. Built for longevity and lasting performance.
  • Wide Application: This tester can detect low current LED lights, making it applicable on trucks with an LED lighting system. For 2017+ Ford/GMC/Chevy models, the 7-way plug position was altered by manufacturer, causing the tester to fit upside down in these sockets. Note: NOT compatible with vehicles that have lamp-out sensors, such as BMW, VW, Audi, Mercedes & Porsche.
  • Plug-N-Play: LED circuit tester effortlessly examines your trailer light circuits, requiring no additional tools. Suitable for a wide range of trucks, boats, trailers, campers, RVs, and other towing vehicles.
