Yes- MOT says "This inspection applies to the one rear fog lamp which is required to be fitted to the centre or offside of vehicles first used on or after 1 April 1980".
I was planning the rear light setup for mine as soon as I'd decided to get a Z300S after I saw Nick's at Stoneleigh 2014, even before I left the site. And that included reversing light, fog light and reflectors. The curvature of the rear tub did not allow them to be fitted as far outboard as I wished but they are all present and giving the effect I wanted.
