Single Electrics
Also known as 12(N), are fitted as standard. They provide power from the tow bar to the lights on a trailer or caravan. If your only going to be towing a trailer this is all you need. You can tow a caravan using only single electrics, but the interior functions of the caravan, such as the fridge, wouldn't have power to them. If you will only be using the tow bar for a cycle carrier we recommend that you still have a single electric socket fitted so that you can power a light board over the bikes.
