The Nilight 4 Way Flat to 7 Way Round Trailer Adapter Plug is a compact traction adapter designed to seamlessly convert a 4-way flat vehicle end to a 7-way blade trailer end. It ensures a tight connection between the vehicle socket and the trailer plug, eliminating any wiggle-room or loose fittings while efficiently transferring power from the vehicle to the trailer.

This adapter is built to function as a 4-pin flat socket converted into a 7-pin blade round type socket. It works with most vehicle wiring components, including turn signals, brakes, reverse lights, and auxiliary power, ensuring compatibility with a wide range of trailers and towing applications.

Constructed with heavy-duty black plastic, this adapter is highly durable and resistant to rust, enhancing both its longevity and appearance. Its well-sealed, spring-loaded cover provides extra protection against dust, moisture, and corrosion, safeguarding the inner contacts from rust or damage. Additionally, the black wire loom keeps the wiring organized and protected, ensuring long-lasting performance.

Installation is quick and straightforward, as the adapter comes equipped with a mounting bracket, screws, and nuts for secure attachment to a trailer hitch or bumper. Simply find the right position, tighten the nut, and the adapter is ready for use. It is perfect for trailers, semitrailers, caravans, and RVs and is commonly used with T-connectors or tail lamp converters featuring 4-way flat car end connections.
