I think that my bar end mirror gives me greater safety and will receive far more use, I would not consider ditching those for a wing light a sensible swap nor one that increases my overall safety.
Why would I wish to make myself less distinctive as a bicycle and look more like a motorised vehicle to the casual/glance observation? How does that make me safer if someone doesn't pay sufficient attention noticing only the blinking amber and mistakes me for a vehicle with greater speed, protection?
How effective are they in broad daylight?
I'll have that they can be the same colour and frequency of car indicators, but same power from what looks like button cell batteries?
The inch+ wide reflective slap bands I wear on my wrists as indicators are larger in area, contrast strongly with skin or the clothing I wear, they are visible higher up in drivers eyeline and stick further out to clearly signal my intention and directional change, 2 of them cost me £4, there is no danger of a hefty bump in the road knocking them off (I've had lights come loose before let alone magnets & they wrap a couple of times around my wrist so will not slip or fall off accidentally, there is no danger that forgetting to remove them will see them vulnerable to theft and they require no power source to be fully operational.
Nowhere in your video do you show these from a following drivers eye viewpoint, you've shot from the front or side only, never from the same.road plane that the driver posing most danger to me is in. I would like to see them shot from a following drivers perspective to see how visible they are past the rider, particularly for the adjusting road position of a right turn, I suspect, if properly visible at all, they could easily be confused for a different orange light on a more distant vehicle and if anything make me less safe rather than more.
I can see that they would fit on drop bar bikes too but would be of very little effect viewed from the front, & again not compatible with bar end mirrors or shifters, also I think a well panniered trip from the supermarket or touring would obscure their effectiveness backwards, as would the riders legs on narrower bars.
How much time.and money and effort will you be putting in to educating drivers that you are pushing a product onto cyclists that is highly unusual to associate with a bike and looks much like they would expect to see on the corner of a car or top of a roadsweeper, utility van etc?
For what they are, they are a good example, up there with the same idea that is incorporated into a mirror,,tho that does give a tad more width and rearward visibility to the flashing parts than your idea, but what they are is still the problem for me and I don't think that you have answered all of the problems bike indicators pose, TBH I'm not convinced there are answers other than your casually & slightly fallaciously dismissed extended arm.
I note on your 1934 & today stick riders you conveniently forget to include any sort of hi viz glove & arm reflective / flashy, these are ubiquitous in cycle and sport shops and more diverse outlets for pennies for reflectives and a pounds for gloves as well as being a staple giveaway at cycle, running, sport events.
Added to which, I am 46 now, as a child I had an orange and reflective armband on my winter coat at my mums insistence & my teen/20+yo kids had reflective + LED armbands handed out for free by primary school more than once many years ago. Little bits of dishonesty by omission are a personal annoyance that put me off the producers as well as the product.
