What types of trailers or vehicles typically use European style trailer connectors?

European style trailer connectors, also known as ISO 1724 connectors, are commonly used in Europe and other regions around the world. They are designed to provide electrical connections between towing vehicles and trailers. These connectors are different from the standard North American trailer connectors, such as the 4-way flat or 7-way round connectors, which are more prevalent in the United States and Canada.
European style trailer connectors come in various configurations, but the most common type is the 7-pin connector, also known as the "ISO 1724 12N" connector. The pins in this connector are used for specific functions related to lighting and other electrical systems on the trailer. Here are the functions typically associated with the 7 pins of the ISO 1724 12N connector:
Pin 1: Rear fog lamp
Pin 2: Reverse lamp
Pin 3: Left-hand indicator/turn signal
Pin 4: Ground
Pin 5: Right-hand indicator/turn signal
Pin 6: Brake lights
Pin 7: Power supply (usually for charging the trailer's battery)
Trailers and vehicles that use European style trailer connectors may include:
Caravans/Campers: Many caravans and camper trailers in Europe use the ISO 1724 12N connector for electrical connections to the towing vehicle.
Commercial Trailers: Various commercial trailers, including cargo trailers, box trailers, and livestock trailers, in Europe may be equipped with European style connectors.
Boat Trailers: Some boat trailers in Europe also use the ISO 1724 12N connector for lighting and other electrical functions.
Agricultural Trailers: Farm equipment and agricultural trailers in Europe may use European style trailer connectors for electrical connections.
Horse Trailers: Horse trailers used for transporting horses or other livestock may have European style connectors for electrical systems.
It's important to note that compatibility between towing vehicles and trailers is essential. If you have a towing vehicle with a different type of connector (e.g., a North American style 7-way round connector), you may need an adapter to connect to a trailer with a European style connector or vice versa.
If you are traveling or towing between regions with different types of connectors, make sure you have the appropriate adapters and check that all the electrical connections are functioning correctly to ensure safe towing operations.
