The Ultimate Guide to the Fiat Ducato Long Arm Electric Mirror (Right Side)
9th Mar 2026
The Must‑Have Upgrade for Ducato, Relay, Boxer & Movano Owners
If you drive a Fiat Ducato, Citroën Relay, Peugeot Boxer, or Vauxhall Movano, you already know how important good visibility is. These vans are the workhorses of Europe — relied on by tradespeople, delivery drivers, motorhome owners, and fleet operators. But with their wide bodies, long wheelbases, and often‑limited rear visibility, the right mirror setup isn’t just helpful… it’s essential.
That’s why the Fiat Ducato Long Arm Electric Mirror with Temperature Sensor (O/S Right) has become one of the most sought‑after replacement mirrors on the market. Whether you’re replacing a damaged mirror, upgrading for better visibility, or restoring a motorhome to factory spec, this genuine Fiat mirror is the gold standard.
Today, we’re breaking down everything you need to know about this mirror — what it does, why it matters, and why choosing a genuine OEM part is the smartest move you can make.

Why the Long‑Arm Mirror Matters

The long‑arm design is specifically engineered for:
- Motorhomes
- Coachbuilt conversions
- Wide‑body vans (2350mm body width)
These vehicles sit wider than standard panel vans, meaning standard mirrors simply don’t provide enough rearward visibility.
The Long‑Arm Advantage
- Wider field of view
- Better visibility past coachbuilt bodies
- Safer lane changes
- Easier reversing
- Improved towing awareness
For motorhome owners, this mirror is essential. For commercial drivers, it’s a major safety upgrade.

Who This Mirror Is Designed For

- Motorhome Owners
Most UK and European motorhomes are built on the Ducato/Relay/Boxer chassis. The long‑arm mirror is essential for wide‑body coach-built models.

If your van has a wider body or you regularly tow, the long‑arm mirror gives you the visibility you need to stay safe.

A damaged mirror is one of the most common fleet issues. Replacing it with a genuine OEM unit ensures compliance and safety.
- Delivery Drivers
Better visibility means fewer accidents, fewer insurance claims, and safer manoeuvring in tight spaces.

There are cheaper alternatives — but they come with compromises:
- Poor fitment

A genuine Fiat mirror ensures:
