Moving stuff can get very complex and I'm not always convinced more is better. A lot of weird stuff happens in our brains with regard to movement perception. Loads of examples highlighting the weirdness but eg in the animated image below dark background (+ grid) is rotating with three stationary yellow dots and a blinking green dot in the middle. Look at the green dot and ... the yellow dots disappear, sometimes all, sometimes just one ... and then reappear but they are not -yellow dots are solid no flashing. It's your brain processing movement and deciding to ignore stuff. (On some screens it doesn't work apparently to do with screen technology and pixel refresh details).

note: on my phone the background isn't rotating so doesn't word but on my tablet it is and does work (both in Safari browser) -Reason for this: I have this website set to not play animations as a few people have highly irritating animated avatars.

If you cover the green dot with something so that you can't see it, the yellow ones still disappear.

Sorry for resurrecting an old thread, I have dual flashing front lights, one flashing rear with brake light function (Cateye), dynamo front and rear lights, I will soon be mounting Knog flashers on my helmet since with my head moving around that will hopefully draw more attention than just another flasher. I've also got a lot of black-in-daylight Scotchlite tape since in daylight it blends in with my bikes black wheelrims, frame, seat (recumbent) and carbon tailbox. With all of this I'm going to make a bracket to attach pedal reflectors to my Speedplay pedals, which will render them single-sided but will mean I am legally compliant and as mentioned further up this thread will make me more visible as they are eye catching at night because they move.

I think it was @fossyant that told us the tale on how he was run over running a gazillion lights on his bike.
From time to time I see setups similar to that described, a more common one is 4 or 5 rear lights. Another I see quite regularly are huge, badly adjusted front lights.

As a driver I find these sort of setups have one thing in common, they create a distraction. I see that something is there but I'm not quite sure what, at a guess it's a cyclist but I'm not certain. It takes longer to decide what the hazard is. I'm not sure this is a good thing.

I find similar with car lights, drivers who adorn the front of their vehicle with additional lights create a distraction as I tend to look at them.

The purpose of lights and highly visible clothing is to send a quick clear message. I'm here, I'm a cyclist. That's all that is required.

Mobile phone use is banned while driving. Why? It's distracting. Anything which distracts drivers potentially creates a hazard rather than preventing one.

Overall I'm unsure about just what cyclists who light themselves up like Blackpool illuminations think they're achieving. I don't understand the thought process or what stimulates it.

I’m going to go with ‘fear of being hit by another vehicle’, Bob.
 
I've never been keen on having something attached to a helmet as fall off and if that hard thing attached lands between road and head the feeble polystyrene will not stop it puncturing into your head. Never happened to me so theoretical and these days academic (I haven't worn a helmet for a few years).

When I used to fly gliders, club rule (unsure about other clubs) had a rule "no baseball hats" as get flung about a bit and/or straps a bit lose or some acrobatics and baseball hats have a button top middle which risks being driven into your skull. No idea if some official being OTT or if a potential risk but it was an enforced rule.

I think you will find that they were more worried about the button damaging the glider's canopy than your skull. The other problem with baseball caps is that the peak restricts your upwards peripheral vision unless you wear them backwards.
 
Which is why I run a "day bright" rear light with a 12 hour run time.
As probably mentioned before, some lights, notably Varia radars, will produce an alert on a head unit if they run low on battery or lose connection completely due to failing in some non-battery manner or dropping off. Not as good as the full redundancy of having two rear lights, but a great deal better than simply not knowing.

Without wishing to sound awkward, why only extra things on a bike but not on a car? If someone drives an old car with no sensors or all the other myriad of extras the driver doesn't seem to crash or be hit more often. The onus is being put entirely on cycle riders and ignoring the car is king mentality. More and bigger cars multiply absurdly and barely pay lip service to environment concerns.

But if the bracket fails and it drops off, or if it dies for some other reason, you still won't notice.

My solution to this is multiple redundant cheapo cateye omnis.

On my Kinesis I use a Raceware bracket screwed into a standard frame fixing at the top of the offside seat stay and a solid clamp on seat post for carbon bikes.

Then I also have my Varia attached to the seat post with a solid clamped mount.

I know s**t happens but two failed lights and brackets on one ride is very bad luck.

To be fair having functioning lights on a bike is actually required at night etc

it is the other stuff that is extra

I read an article some time ago about whether cycle helmet should be compulsory
It included an interview with a brain surgeon who worked closely with the A&E in the hospital
and so had seen a lot of head injuries from road accidents

His comment was that cycle helmet would help in a large percentage of the bicycle crashes he sees
but that he only sees the ones with brain injuries - so a lot of cycle crashes WITH helmets never come to his attention

AND - he reckoned that if you want to make helmet compulsory for any road users
he would do it for car driver
He sees a lot of car drivers were a side impact has caused their skull to impact the side of the car and they end up with him


but I reckon a government would fall if they tried to make a helpmet compulsory when driving a car!!!

Imagine the fallout if it was announced that at least one practical thoroughfare was to be closed to cater purely for ease of cycling in every part of the country. There would be uproar. This is the mentality that needs changing. It is done in many other countries but as always the UK is so far behind the curve. 20 mph was the end of the world to make it safer for some.

I agree

I have seen to of those things where they try to stop cars using a residential road as a cut through by putting big planers across it
Hence bikes and walkers - and mobilirt scooters - can get through but not cars etc

and the "local community groups" go beserk because the cyclist are being given a nice quiet route through the town at the expense fo the cars

no mention of mobility scooters or pushchairs
but bikes are allowed and not cars!!!
