Maypole 7 Pin 6m Straight Extension Lead (Plug To Socket) for Trailer Lighting
Product description
What it is and what it does
The Maypole 7 Pin 6 m Straight Extension Lead is a 6‑metre, seven‑core trailer extension cable designed to provide lighting functionality from a vehicle to a trailer. It features a 7‑pin plug on one end and a 7‑pin flying socket on the other, offering a straightforward way to power trailer lights in a single, straight run.
Why it matters
For caravans, horse trailers or light utility trailers that use the ISO 1724 standard, a reliable extension lead helps ensure that indicators, brake lights and tail lights stay visible and compliant on the road. The 6 m length gives you flexibility for typical tow setups without forcing awkward cable routing.
What stands out

On the paper, the cable is a length that balances reach with manageability. It’s built as a rigid, seven‑core configuration in a straight cable, which helps keep wiring organised and reduces tangling compared with multi‑elbow extensions. The kit is packed in a re‑useable zip bag, making storage neat between uses.
Who it’s for


This extension lead is well suited to motorists who frequently tow trailers that require a seven‑pin ISO connection and prefer a single, simple cable route rather than shorter, modular leads. If your vehicle and trailer both use ISO 1724 lighting, this lead should slot in as a practical, no‑fuss option.
When it makes sense to buy
Consider this lead if you need a dependable, middle‑length extension to reach from your tow hitch to the trailer’s lighting connector without creating clutter. It’s a sensible choice for occasional towing or for keeping a spare lead in the boot or shed.

When it might not be the best choice
If your towing setup requires more flexibility in routing, you might prefer an extension with bends or a different jacket material. Also, if you need a longer reach than 6 m, this model won’t cover that without a separate solution.
What to check before purchasing
- Confirm your trailer uses a 7‑pin ISO 1724 connection and that the lead’s plug and socket are compatible.
- Consider your preferred storage solution, the zip bag is handy, but ensure it’s robust enough for outdoor use.
- Check the weather exposure expectations for your tow setup, the base description doesn’t specify IP rating or weatherproofing.

Practical usage example
If you’re hitching a trailer across town for a weekend load, you can drop the lead from the tow ball, route it beneath the hitch, and connect the trailer’s lighting without trailing cables across the drive. The straight design keeps the wiring tidy and avoids kinks when making sharp turns at the site.
FAQ
- Is this lead weatherproof? The base description does not specify weatherproofing or an IP rating, so use with sensible caution in wet conditions.
- Will it fit all 7‑pin ISO trailers? It’s designed for 7‑pin ISO 1724 connections, which covers common trailer lighting systems.
- Can I use it as a spare or for storage in a shed? The included zip bag supports light duty storage, for heavy outdoor use consider additional protection.
Is it worth it?
Worth considering if your setup uses ISO 1724 7‑pin connectors and you need a tidy, 6 m straight lead with a plug to socket configuration. It may not be the best choice if you require greater flexibility in routing or extended length.
