Oyviny 7-Pin Trailer Connector Socket + 7-Way & 5/4-Pin Trailer Light Tester

This 7-blade RV trailer tester is designed for long-lasting use. Crafted from durable ABS plastic, it will never rust or corrode. The tin-plated copper terminals ensure great conductivity.

The 7-pin male plug on this tester comes ready to splice into your existing vehicle wiring. This 7-way male trailer connector allows you to test the taillights, brake lights, reverse lights, turn signals, trailer brakes, and auxiliary power.

For a reliable and long-lasting connection, the housing of the RV male 7-way blade plug is made from heavy-duty black plastic to prevent rusting. The brass terminals provide better conductivity and enhanced corrosion resistance.

This trailer light tester is a 3-in-1 design. It combines a 5-way circuit tester and a 7-way trailer light tester, allowing you to test the 4-pin flat, 5-pin flat, and 7-blade connectors. It is easy and quick to use when testing trailer circuits on most trucks.

The upgraded double-sided design of the tester allows you to read the LEDs from both the top and bottom sides, making the process more convenient.

This 7-way RV trailer tester can also be used as a 7-way to 5-way trailer adapter, converting the vehicle-side 7-pin output to a 5-pin flat adapter to connect to 5-way or 4-way trailer light plugs.

The bright LED indicators on the 5-way and 7-way trailer light tester provide a clear visual representation of each electrical function. By plugging in the light tester and checking the green LEDs, you can easily identify any wiring issues.
