I had Googled RIST thinking the poster might have meant something about the shape of the plug. I should have Googled RISTS. :(
I've never heard of them before.
Thanks for the info. That makes sense as it has a tow kit however the trailer light indicator on the dash has never worked and I thought they may have not used the Rover loom. Thanks for the help! Rovering:)
The light should work whether the genuine socket is used or not. Is there a globe in there?
