Here's a primed replacement wing mirror cover cap for the right side (driver's side in the UK) of a Range Rover Mk4 L405, model years 2012 through 2022.
From Ultimate Styling, this is a brand new clip-on type cover, made of plastic and ready for paint.
It's primed, so you can color-match it to your ride.
Fits all those years: 2012, 2013, up to 2022.
One piece, super easy install – just clips right on over the existing mirror housing.
