7 Pin Plastic Socket - LG1350

7 Pin Plastic Socket – LG1350

The 7 pin plastic socket LG1350 is a proven, no-nonsense solution for standard trailer road lighting. It’s the familiar 12 V towing connection used across Europe for tail, brake, indicator and fog lights on trailers and caravans. Ideal for new builds, repairs and extending existing 7 pin trailer light cables where reliability and simplicity matter.

This 7 pin trailer socket is designed for road lighting only, so it focuses on what most fleets actually use day to day – the core lighting functions that keep trailers road-legal and visible. It’s the traditional 12 V 7 pin format trusted by towbar fitters, agricultural workshops and commercial fleets for light-duty and medium-duty trailers.

Although the 7 pin standard is slowly being superseded by the European 13 pin plug on newer caravans and trailers with reverse lamps, there’s still a huge installed base of 7 pin systems in service. That’s where this socket earns its keep. It keeps existing equipment running, supports repairs, and gives you a straightforward interface when you don’t need full 13 pin functionality.

The plastic body keeps weight and cost down while offering a durable, corrosion-resistant housing for the contacts. Internally, all pins are clearly marked, so wiring is direct and unambiguous. The insert comes out easily, giving proper access to the screw terminals. There’s only one way to reassemble it, which prevents misalignment and awkward refits during roadside or workshop repairs.

Installation is simple for any competent auto electrician or workshop technician. Disassemble the socket, strip and connect the wires to the correctly marked pins, tighten the screws, then refit the centre section into the housing. The LG1350 is ideal for extending 7 pin trailer light cables, retrofitting to older trailers, or replacing worn, cracked or corroded sockets on towing vehicles.
