7 Pin Plastic Socket for Vehicles - LG1356

7 Pin Plastic Socket for Vehicles – LG1356

The 7 pin plastic trailer socket LG1356 is a straightforward, proven connector for 12 V road lighting on trailers, caravans, and light plant. It’s the classic 7 pin system most fleets already use, ideal for tail, brake, indicator, and fog lights where a reliable, easy-to-wire towing socket is needed. Built for everyday use, it gives you stable lighting connections without fuss or overcomplication.

This 7 pin vehicle socket exists for one reason. To keep road lighting on your towed equipment working every time you plug in. No menus. No diagnostics. Just a solid mechanical connection that workshop teams know, trust, and can service in minutes.

LG1356 is a plastic 7 pin, 12 volt road-lighting socket, commonly known as the standard 7 pin towing socket used across Europe and the UK. It’s designed for lighting circuits only: indicators, tail, brake, fog, and number plate lamps. Many fleets still standardise on this connector because it matches the wiring on the majority of existing trailers, plant trailers, and older caravans.

This format is gradually being replaced on new European trailers by the 13 pin towing system, especially where reverse light and extra functions are now a legal requirement. But that change is slow. So for existing fleets, hire stock, farm trailers, and general-purpose plant, the 7 pin socket remains the practical choice. LG1356 keeps you compatible with that large installed base, at low cost and with parts that every auto electrician understands.

Installation is deliberately simple. The centre insert is removable, so you can pull it out, access the screw terminals, and wire each core to its marked pin. The pins are clearly identified; the socket body only assembles one way, which cuts wiring errors. Any competent technician can fit or replace one in a short workshop slot, keeping downtime off your maintenance sheet.

Key Features

• Standard 7 pin towing socket – supports road lighting circuits only (indicators, tail, stop, fog, number plate) for trailers and caravans.
• 12 V plastic socket housing – ideal for cars, 4x4s, light commercials, and vans running standard 12 volt systems.
• Most commonly used trailer connector – matches the existing 7 pin plug found on the majority of general-duty trailers and older caravans.
• Simple, screw-terminal wiring – the centre core removes for easy access, speeding up installation and fault-finding in the workshop.
• Pins clearly marked – reduces wiring mistakes and helps standardise connections across your fleet.
• One-way assembly design – the insert only fits back in one position, helping keep pin allocation correct after service or repair.
• Suitable for fleet maintenance and retrofits – keeps legacy trailers and equipment in service while newer units move to 13 pin as required.
• Cost-effective, proven design – a trusted solution where you need robust lighting connections without adding complexity.

Ideal Applications

• General-duty trailers for builders, trades, and rental fleets using 12 V 7 pin plugs
• Caravans and leisure trailers with traditional 7 pin road-lighting connections
• Farm and agricultural trailers where simple, serviceable electrics are preferred
• Plant and equipment trailers behind 4x4s and light commercials
• Service replacements on vehicles already equipped with 7 pin towing electrics
