Paul, if you send
these good folks a picture I'm sure they could help you. Like you I think it's a Disco one but maybe there are a few versions of them.
I recall a German colleague on here getting stuck away from home and a Landy dealer had a replacement on the shelf.
Maybe a similar story happened here, but if it was mine, you have a very good memory, Richard. Only in my case it was the rotary switch (in the turn signal lever on the left side of the steering column) for the driving lights. I had only parking light by the error. Whether in the ARP4 the same parts were installed I do not know of course. But in my 2014 4/4 it is from a Freelander!, I don't know what generation of Freelander, but up to 2015 because it happened that year.
In the link below is my original post about the breakdown from 2015 with text under the last picture.
Really Richard, if you still know that then all respect for your gray cells.
