Spina in plastica a 3 pin - LG1370

3 Pin Plastic Plug – LG1370

The 3 pin plastic plug LG1370 is a simple, proven solution for 12 V road lighting connections on light trailers and caravans. It’s designed for straightforward towing electrics where you only need core road lights, not full auxiliary functions. Robust plastic construction and clear pin markings keep wiring quick, tidy, and reliable.

This classic 3 pin trailer plug exists for one reason. To give you a stable, no-nonsense connection for basic road-legal lighting on towed equipment. Where older or lighter trailers don’t need reverse light or auxiliary feeds, this plug keeps things easy and keeps costs down.

It’s 12 volt plastic construction, light but tough enough for everyday use around yards, farms, and workshops. The internal insert removes completely once you undo the body, so you get full access to each screw terminal. Each contact pin is clearly marked. You match wire to pin, tighten, and reassemble. There’s only one way it goes back together, so alignment isn’t a guessing game.

This style of 3 pin towing plug is still widely trusted by auto electricians and agricultural users across Europe for basic lighting circuits. It’s especially useful for legacy equipment, older trailers, and situations where a quick repair or replacement is needed without converting the whole system to 13 pin European towing electrics. As reverse lights become mandatory on newer trailers, 3 pin will gradually phase out there, but for existing fleets it remains a practical, cost-effective choice.

So if you’re maintaining existing gear, or keeping a small fleet of work trailers on the road, this plug helps you standardise the hardware in your workshop. No special tools, no complex loom changes. Just a clean, simple 3 pin connection you can wire in minutes.
