Oyviny 7 Way Blade to 12V Power Adapter with LED Circuit Tester

This durable 7-blade RV trailer tester, made from corrosion-resistant ABS plastic, ensures long-lasting use. The tin-plated copper terminals provide excellent conductivity. The Multi-Tow Trailer Adapter offers versatility, converting the 7-way flat blade to a 4-way or 5-way trailer connector, while also adapting the 7-way to a 12-volt power cigarette lighter socket. However, it is important to note that this adapter is not compatible with vehicles equipped with a lamp-out sensor.

The 12V power outlet can be used to power a variety of accessories, such as air compressors, spot/flood lights, inverters, freezers, and electric coolers, in the back of your truck. This convenient solution allows you to place the 12V outlet where it's needed, with a simple plug-and-play setup, eliminating the need for complex wiring from the battery to the truck bed.

The 3-in-1 design of this trailer light tester combines a 5-way circuit tester and a 7-way trailer light tester, enabling you to test the 4-pin flat, 5-pin flat, and 7-blade connectors. This makes it easy and quick to test trailer circuits on most trucks. The upgraded double-sided design allows you to read the LEDs from both the top and bottom sides, enhancing the convenience and efficiency of the testing process.

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, allowing you to connect to 5-way or 4-way trailer light plugs.

The versatile trailer wiring tester can be used to test six separate trailer light functions, quickly confirming the functionality of taillights, brake lights, reverse lights, turn signals, electric trailer brakes, and the 12V auxiliary power on your vehicle. This comprehensive testing capability ensures that your trailer's electrical system is fully operational, enhancing safety and reliability on the road.
