7 Pin (Single electrics, one socket)
This configuration offers all obligatory rear light systems on trailers, lightboards and cycle carriers.
7 Pin (Twin electrics, two sockets)
This offers additional electrics for caravan services and reverse lights (if fitted).
13 Pin (European Socket)
This can be wired with or without caravan services. In the market place today, any new trailer that meets EU requirements cannot work through a standard 7 pin socket, therefore the 13 pin socket is becoming more popular. It can be wired in a ‘single’ format for cost effectiveness or wired for full caravan services ‘twin’ format. Many detachable towbars now only allows for one socket fitment. This means that in the near future 13 pin electrics will become the standard format.
