12 Pin LED Plug and Socket
12 Pin LED plug and socket with stainless steel terminals for Caravan and Aux Batteries. Led’s are located under the cover on the right and the left side of the Pins.
A good tip is to spray corroded terminals with WD40. As a result, connections come back to life and become electrically conductive again.
However, this fix is short-lived and only provides a temporary solution. The best answer is to buy a quality set of trailer LED plug and sockets.
12 pin LED connectors provide evidence of electrical conductivity, at a glance. This visual check makes caravanning easy.
Problems associated with trailer plugs
- Corrosion of terminals
- Water ingress
- Dirt ingress
- Cable separation from terminals
The greatest cause of trailer plug connection problems is unsoldered and ineffective connections at plug terminal and at the trailer lights. The simple solution is to twist the cable ends, solder the copper tips then insert into the plug ferrules and tighten.
Generally, pin connectors are brass or poor quality brass alloy. Trailer Vision invented LED connectors with stainless steel screws in their terminals in an effort to combat poor connections.

Bad connections are a result of oxidised terminals or bad connections. To eliminate bad connections, Couplemate recommends soldering the ends of each cable end before insertion into the ferrule.
Trailer Vision has produced a combination of stainless steel screws with plated brass terminals to help prevent breakage and ensure tight contact between socket and plug.

Testing Breakaway Battery
- Disconnect the trailer plug from the vehicle.
- Pull out the pin in the breakaway switch to activate the electric braking system.
- The BLUE flashing LED in the trailer plug must flash to indicate breakaway battery energy source.
