so in an attempt to take this daft thread off topic and into an area worth discussing... why is a set of bike lights that do not carry the BS kite mark 'insufficient' ?
They're not sufficient to count as legally lit simply because the law says it must carry the BS or equivalent European marking - unless it only has a 1-4Hz flash mode of 4cd or more, or if it's a headlight on a vintage bicycle. I don't think it entirely makes sense, but that is what is required to be legal and everything else is a matter of opinion (for example, I think flashing lights are daft because a motorist may glance when they're in the "off" phase).
Back in the days if D batteries and bulbs i had various sets of bike lights which all had a pretty little kite mark stamped on them... but gawd the lights were sh!te, especially after about 20 minutes when a rich tea biscuit would have been brighter.
Yeah, I've done my time grubbing along searching for the road with old D-cell lights and that's overstating it slightly but no, they weren't good. It's rather disappointing that lights now aren't absolutely perfect with the brighter LEDs, but they aren't.
I've never noticed a single kite mark on any of my LED bike lights, but they certainly seem to work a lot better than the old (pre-LED) ones. They may not have a kite mark but i can see in front of me and can be seen, for hours and hours rather than a mere 20-30 minutes... so what's so insufficient about them???

Most commonly, the beam cut-off is too far above the brightest spot, so you have the awful choice of whether to aim it closer to your wheel than you really want, or to aim it where you want it and consequently dazzle oncoming road users, which is rather rude when it's a cyclist and inviting serious injury when it's a motorist.
There are a few lights with good lenses and no standard marking, but they seem depressingly rare. The cycling light market seems almost completely broken, with shops selling mostly awful lights marketed on meaningless lumen and Watt statistics, with most cyclists either not caring whether they're nasty to others or disagreeing that it is nasty to shine a light in others' eyes.
Does anyone know the costs involved in getting products tested to British Standards??? I can't see it being a free service.
It's £90 for the spec, so I doubt it's cheap, but it's a one-off product development cost. I suspect getting a German K marking may be cheaper and better-respected than our outdated standards.
IF drivers very definitely see cyclists dressed in black, riding black bikes, without lights - and give them a wide berth, how come do they decide to come so close to me, lit up like a ****ing Xmas tree, high-vis waistcoat/arm bands/ankle bands, and wheel lights?
Simples - I have lit myself up so that they can improve their aim! Sure, it's a tiny minority, but I do get pissed off when unlit ninja is given space, and I get the punishment pass.
You may be joking, but you're effectively peacocking, making it easy for motorists who aren't paying full attention to look at your wonderful plumage and, as I was told when learning, they steer where they stare!
I feel that good steady lights which you can see by and be seen by, ideally with a back light with a large illuminated surface that makes it easy for others to judge position and distance, plus the distinctive dancing pedal reflectors (for front/back) and wheel reflectors (for side) are sufficient. Any funny shaped clothing on top of the vehicle is a distraction. If they can't see the lights and reflectors, they probably aren't going to see anything you do and that's a different problem!
