13-PIN UNITRAILER trailer towbar socket

13-PIN UNITRAILER trailer towbar socket

The 13-pin trailer socket is an essential accessory for anyone planning to tow a caravan, other trailer over 750 kilograms, or a bike rack equipped with reversing lights. This socket is designed to provide a reliable electrical connection between your vehicle and trailer, ensuring that all of your trailer's lighting and electrical systems operate correctly during transport.

The 13-pin socket is designed to be mounted on the towbar of the vehicle, used to connect the trailer. Thanks to its design, it allows signals to be sent to elements such as reversing lights, indicators, brake lights and interior lighting in the caravan. This is especially important when towing heavier trailers, where a more extensive electrical connection is required than in the case of the standard 7-pin socket.

Made of durable materials, the socket is resistant to weather conditions and mechanical damage, which ensures long-term and reliable operation, even in difficult road conditions. Thanks to its use, you can be sure that your trailer is fully equipped and safe on the road, which increases the comfort and safety of travel.
