This 12V trailer adapter cable (7-pin vehicle to 13-pin trailer) with a 0.5-meter lead provides a secure, weatherproof electrical link between a towing vehicle fitted with a 7-pole socket and a trailer, caravan, or hitch-mounted bike carrier equipped with a 13-pole plug. Fully compliant with DIN ISO 1724 (7-pin) and DIN ISO 11446 (13-pin) automotive standards, it ensures seamless transmission of all essential lighting signals, including tail lights, brake lights, indicators, and license plate illumination. The integrated 0.5-meter flexible cable accommodates vehicle-trailer articulation during tight turns and maneuvering while preventing cable strain or road dragging. Constructed from impact-resistant and weather-resistant polymer housings with protective spring-loaded cap seals, it guards contact pins against moisture, road grime, and corrosion for reliable towing.
