I carry a spare set with me – since learning the hard way – that if they get damaged in mainland Europe – it's impossible to get a right-hand drive set.
Here is the label on that spare set. Note though, that I have the saloon – so no rear wiper.
It never occurred to me that they have left and right hand wipers. Funny thing, my car was delivered with one left hand and one right hand wiper. The wrong hand one was replaced by dealer, but I was left wondering how they could have screwed up the assembly. Mystery solved!
