EU 12V 13 Pin Socket Box Aluminum for Caravan Towbar Wiring Towing Electric Lights

Every object that you attach to your car, has to be powered by electricity so all the lights are working. An essential feature that ensures safety in traffic. The connection between the car and the bike carrier, trailer, caravan, boat trailer or horsebox is created by putting the plug of the object you wish to tow in the socket on your car. The two plugs that are most common are the 7-pin and 13-pin plugs.

In general, bike carriers are equipped with a 7-pin plug. The same applies to older trailers, boat trailers or horseboxes. In more modern models of these tow objects, the 13-pin plug is more and more common. A caravan always has a 13-pin plug.
