Never noticed them before - ever, so naturally presumed they had been fitted recently.
Cadets 8242-52 were delivered new with flip dots all round.
Once they lost GNE livery in favour of branding, they gained LED displays on fronts only, keeping flip dot on side and rear.
Most of the rear screens now show nothing, so if you see one that works, it is probably just shock to actually see it working.
