Oh come on HF2300 - do you really mean to suggest that at night Hiviz is better than decent lights?
But that implies seeing high vis as an alternative. I don't think anyone pro-visibility would suggest high vis is an alternative to decent lights. Equally, I'm sure that's not what I said. Perhaps I misread the intent of your original comments. I'm convinced, though, that high-vis is a useful addition to good lights, bike reflectors, etc.

There's no way hiviz can possibly perform as well as lights at night, because it's passive
If we're talking the brightness the viewer will perceive, I'm not sure that's the case. It will depend on the luminance of the reflective material, the power of the light shining on it, angle of incidence etc. vs. the brightness and beam pattern of the light - but that's probably a fairly esoteric debate.

...and it doesn't always work - eg the fluo doesn't work at night, and the reflectives won't in a side-road example.
Agreed with the fluorescent, though it's still better than black / dark. I don't see why the reflectives won't work in a side-road example, though perhaps we're thinking of different types of high vis or different examples.

Any time visibility is reduced, our lights should be on as per the highway code.
Oh, absolutely, but have I said they shouldn't? Or perhaps that's just a general comment.

Given that only the reflectives are useful at night, then the on-bike reflectors are plenty. Lights are much more effective, and if your lights have no side-on visibility, that's a failing you should be fixing asap. OTOH I don't think side-on visibility plays much part in collision prevention, at least nothing by comparison with most collision types.
Again, I think we see things differently (I haven't got the patented Bent Mikey supervision (TM)!) Yes, that's why the bike reflectors are there, but I don't think they're plenty and I think a good bit of high vis is a useful adjunct. Side on visibility - well, OK, most decent rear lights work to the sides, but I'm not so sure many of the front lights do from what I see, and even the rear lights IME tend to be focused and much more visible to the rear.

...but having drivers look in the first place, notice...
Just to go back to this a minute, yes, in an ideal world, everybody (cyclists and drivers) would observe fully and act on what they've observed. In the real world for a million reasons it ain't like that. If I get noticed because a half asleep driver's caught a flash of yellow or reflective in the corner of his eye I'll take that, thanks.
Sh1t, I seem to have rushed in where EMD and others fear to tread and taken on BM in a high vis debate. Oh well...
