The XL Defender Wing Mirror replaces the standard mirror head used on all 90/110/130 Defender models. The increase in glass area of the XL Defender Wing Mirror combined with the convex glass profile creates a greater field of vision to the side of the vehicle. The surface area of the XL Defender Mirror Head measures 245 x 140 (mm) compared with the standard mirror glass area of 198 x 124 (mm). Replacement is straightforward. The Defender XL door mirror uses the same clamp fixing at the standard mirror head.
