3-core round automotive DC cable in 0.75, 1.0, and 1.5mm² cross-sections. 12V/24V rated. For vehicle and trailer 3-wire circuits including lighting, horn, and control wiring.
This 3-core round trailer cable is designed for 12V and 24V DC vehicle-to-trailer electrical connections — supplying power to lighting, braking systems, reversing cameras, and caravan accessories. The cable uses colour-coded cores for each function to simplify installation and fault-finding, with PVC insulation and sheathing rated for the UV exposure, water splash, and mechanical abuse of road use.
Suitable for vehicle 3-wire control circuits, trailer 3-wire lighting, horn and accessory wiring, automotive DC distribution. The flexible PVC construction maintains pliability in the full range of road temperatures, and the colour-coded core identification matches the standard wiring conventions for trailer connectors across the EU, AU, and North American markets.

7-core cables match the 7-pin connector standard (ISO 1724) for most road trailers. 13-core cables match the 13-pin connector (ISO 11446) for caravans and trailers with additional functions. Always match the cable core count to the connector standard used on your tow vehicle.
LED lighting draws very little current — 0.75mm² is adequate for lighting-only circuits. Brake controllers, refrigerators, and electric winches require 2.5mm² or larger. Size the cable to the highest-current function on that circuit.
Trailer cables are exposed to road water, salt spray, and temperature cycling throughout their service life. Tinned copper conductors prevent the corrosion that causes resistance to build at connector pins and termination points — the most common cause of trailer lighting faults.
