Having been rear ended whilst stationary in poor weather in a previous Mog, with the usual "didn't see ya mate" I really want maximum visibility from reflective plates
I've read this several times on this forum over the years. so I've always 'tested' this opinion when driving at night, in fog. mist, snow, torrential rain.or a combination of them etc.
In every instance I been able to view the rear lights many hundred metres before I've been able to pick up any sign of the number plate. Even the rear red reflectors make themselves obvious before I get a hint of reflection from a numberplate. I am quite happy that my (legal) black and white plates have zero mpact on the rear visibility of my Mog.
I do however stick my LED sidelights on when visibilty gets poor, I have a pair of high level additional LED brake lights, and a pair of LED fog lights (which I use actively - turn them off if I have a car a normal driving distance behind me, and then turn back on if there is no-one)
