For your trailer's lighting to function reliably, flawless wiring is essential. Whether you need to replace a corroded plug or are looking for an adapter for a new towing vehicle, you will find the right solution at trailer.one.

Plugs and Sockets (7-Pin & 13-Pin)

We stock standardized connectors for all common trailer types. Choose between the classic 7-pin version for unbraked trailers or the modern 13-pin system, which supports additional functions such as reversing lights or permanent power for caravans.

Adapters: Ensuring a Perfect Match

Does your trailer plug not match your car's socket? No problem. Our robust short adapters bridge the gap between 7-pin and 13-pin systems in an instant – secure, durable, and weather-resistant.

Pre-assembled Wiring & Wiring Looms

Rewiring a trailer doesn't have to be complicated. We offer:

• Bayonet Wiring Kits: Simple plug-and-play systems (e.g., from Aspöck) for connecting rear lights.
• Bulk Cables & Single Wires: High-quality automotive cables for custom repairs.
• Junction & Distribution Boxes: For clean and waterproof distribution of the electrical system on the chassis.

Look for our "Trusted Aftermarket Product" seal on our electrical components – certified quality for your trailer's electrics.
