Ring 12N metal socket with rear fog cut-out – ideal for horseboxes, caravans and trailers
This 12N metal socket from Ring Automotive is a tidy, tough little bit of kit that does exactly what you’d expect: give a solid electrical link between vehicle and trailer while letting you cut out the rear fog when needed. It’s a sensible step up from the flimsy plastic sockets—perfect if you’re fitting a horsebox, caravan or trailer and want something that will take a bit of stick from the weather and everyday use. Compact, lightweight and built for the road, it’s the sort of thing that won’t let you down when you need it.
key features
- Robust metal 12N construction for strength and long service life — made to withstand regular use.
- Rear fog cut-out to stop unwanted fog-lamp activation on trailers — handy in poor visibility or when towing livestock.
- Designed to match standard 12N pin layouts, so it’ll fit most systems used on horseboxes, caravans and trailers.
- Relatively straightforward to fit for competent DIYers — simple wiring and secure mounting give a neat, professional finish.
- Compact size and low weight (approx. 114 g) make it easy to handle and replace.
installation and compatibility
Most people will find this socket straightforward to wire into an existing 12N system — it follows the standard pin layout, so replacing a worn or damaged socket usually plugs straight in without too much faff. That said, it’s worth giving the vehicle’s wiring and fuse protection a quick once-over before you start: if the wiring is old or corroded, a new socket won’t cure underlying faults. If you’re not confident with wiring, a short trip to a local fitter or auto-electrician will save time and headaches.
typical use cases
- Fitting to a new or replacement towbar electrics point on a horsebox to ensure reliable trailer lighting control.
- Upgrading caravan tow electrics to a metal socket for better durability on long trips.
- Replacing a damaged or weatherworn socket on farm or commercial trailers where dependability matters.

why choose this Ring socket?
Ring is a well-known name in vehicle electrics and this metal 12N socket is a practical, no-nonsense upgrade from the usual plastic options. The rear fog cut-out is a proper useful feature — saves accidental fog light use when towing in mixed weather. It feels solid in the hand and is built to last, so you’re less likely to be faffing about with snapped or brittle parts after a season of use. That said, while it provides a reliable connection point, it won’t fix intermittent lights caused by bad wiring; it’s best thought of as a durable, cost-effective upgrade for dependable trailer electrics.
