Trailer Extension Cables – 7-Pin & 13-Pin (5–10 m, Waterproof)

Premium trailer extension cables designed for flawless transmission of electrical signals (tail, brake, turn lights) from your vehicle to the trailer. These cables extend the reach of your standard wiring, which is especially useful for longer trailers, caravans, or when using a separate light board on a boat. Built with high-quality materials, they resist moisture, dust, and vibration. All models are 12V compatible and meet European safety standards.
Variants & Uses:

• 7-pin cable (socket + plug), 5 m: Ideal for small trailers when the factory cable is too short.
• 7-pin cable (socket + plug), 7 m: Great for medium trailers or when a bit of extra reach is needed.
• 7-pin cable (socket + plug), 10 m: Perfect for large trailers or using an independent light bar (e.g., transporting a long boat).
• 7-pin cable (2 x male plugs), 7 m / 8 m / 10 m: Special extensions with two 7-pin male connectors for custom setups and retrofits. Useful for non-standard connections or replacing worn connectors.
• 13-pin cable (2 x male plugs), 5 m / 7 m / 10 m: Extensions for modern trailers and caravans using the 13-pole system (ISO 11446). Provide full functionality (incl. fog and reverse lights) over longer distances – ideal for towing a caravan or large boat trailer.

Installation is quick and easy – simply plug the extension between your existing trailer plug and socket. These cables are especially handy for boat owners launching into water: the extra length lets you remove trailer lights while keeping the electrical connection safe and dry. With these professional extension cables, you'll ensure flexibility and safety on the road when towing any type of trailer.
