Comparing Milenco Adaptor – Lights Only – Car 13-Pin to Caravan 7-Pin (1717) vs Milenco OptiMate 6 – 12V Smart Battery Charger, Maintainer & Desulfator: Which is Right for You?

The Milenco Adaptor – Lights Only – Car 13-Pin to Caravan 7-Pin lets you connect a trailer or caravan fitted with a 7-pin plug to a vehicle with a 13-pin Euro socket, for road lights only.

What it covers

This adaptor converts the vehicle's 13-pin socket down to a 7-pin trailer connection, providing a secure, weather-resistant link for indicators, brake, tail and fog lights. It's specifically for road lighting — Milenco is clear that it isn't intended to power auxiliary caravan circuits such as the fridge feed or battery charging, which need a full 13-pin to 12S/12N setup instead.

Fitting

It's a simple plug-in fit with no wiring involved, and compact enough to keep in the glovebox as a spare for whenever you need to tow behind a different vehicle. Product code 1717.

Before you tow

Push the adaptor fully home until it latches, and check that all lights are functioning correctly before setting off. Store it dry when it's not in use to keep the connection reliable.
