Thanks to all the gods. 6500 lumens! I think you can have either 5000 or 1500 or all 6500 lumens. Thankfully now we will not only be able to blind everyone else on the road or trail, but we can now cause their eyeballs to burst into flames and maybe hopefully their heads will also explode. Yeah!!!!!! This one for their rear light is weird, quote "A sleep mode is triggered after one minute of inaction to save power, any vibration will immediately re-activate the unit". So the light will go out while waiting at an intersection? Really? Nobody raised their hand during the design review? Was there even a design review? First, their definition of "sleep mode" may not be "goes out." It could, I suppose, just become much dimmer. In any case, it would be easy enough to jiggle the bike a bit to turn it back on. Not very smart on the part of the design engineers. But it's probably not necessary. Ohio law specifically permits lights that go out when the bike is stationary, ... Not a smart decision by the lawmakers. ... and there's never been a report of a death or serious injury caused by that feature. Grandpa drove without a seat belt all his life and never go hurt, so ... Grandpa also rode his bicycle without a six foot tall safety flag, a siren, a bell constantly and automatically ringing every time he moved, pads on his knees, pads on his elbows, body armor protecting his spine. Why are you not using all those measures? (Actually, maybe you are. With you, we never know.) BTW, it even happens from the front, even by police officers: https://fox2now.com/2018/07/30/polic...hone-in-video/ Nothing can replace bright light other than even brighter lights. Which both of my bikes have. Joerg, you're the master of the worldwide search for the vanishingly rare exception. That is NOT a common crash type, as any dispassionate search of the literature would shoe. And you have no evidence that your daytime headlight would have prevented it. Looks like the video has been taken down, at least fox2now.com can't find it. Works fine here. Works for me now, no more "video unavailable". ... The accident happened in broad daylight, no vehicles save the cop SUV and the cyclist visible for miles, cyclist waiting at an intersection, I think for a stop sign. Total f*up on the part of the cop, who was more or less apologetic. A daytime running light would not have helped. Not true. I clearly found that drivers notice me much better with bright lights. Even in the corner of their eyes is enough because it "distracts" them in a good way. All it takes is noticing a cyclist a second or two earlier and a collision can be avoided. Seriously? The cop would have looked up from his phone if only the cyclist had had a light? Sounds like magic. Easy to try. While distracted with some chore in your home, have someone walk towards you pointing a bright but not blinding LED flashlight. It works. A human eye is not insensitive in the directions where one does not look, just less sensitive. The "muffling effect" needs to be overcome and intense light is just about the only method to achieve that. This wasn't inside, it was outside in bright daylight, looked like hardly a cloud in the sky. Try this in daylight. It works. ... A really bright light is required to make much difference in that case. Bingo! Now you know why I have bright lights on my bikes. I experienced it again yesterday. I had to ride through city streets for many miles, partially at max speed. With the light fully on nobody cut into my path. Without lights that is different. Other clue: You are driving a car, looking ahead into traffic as you are supposed to do. The dashboard becomes largely unnoticed except for the occasional glance at the speedometer. However, when the yellow check engine light, the red oil pressure light, the overtemp light or the low fuel light comes on it is immediately noticed. Same if someone behind you flashes their headlights even while you aren't looking into the rear view mirror. That only happens if you have the habit, perhaps not completely conscious, of scanning the dashboard. How do you know it's "immediate"? You notice it when you notice it, and if it's 10 seconds after the event that's not a big problem, unlike the case for traffic on the road. If bright enough or if a less bright light in flashing mode I see that immediately. An airline pilot could even lose his license if he didn't. If bright enough... that is exactly what I said, isn't it. But a great many cars do not have bright warning lights. As for airline pilots... I can't speak for the airlines but USAF bombers have a very bright master warning light located at eye level on the instrument panel that comes on if any of the individual warring lights are illuminated. See https://en.wikipedia.org/wiki/Annunciator_panel "More complicated aircraft will feature "Master Warning" and "Master Caution" lights/switches. In the event of any red or yellow annunciator being activated, the yellow or red master light, usually located elsewhere in the pilot's line of sight, will illuminate. In most installations they will flash and an audible alert will accompany them. These "masters" will not stop flashing until they have been acknowledged, usually by pressing the light itself" You have exactly described what I mean. My front annunciator to car drivers is roughly in their line of sight and very bright. The rear one isn't so bright put pulsates. Not irritatingly but gently dimming up and down in random fashion like police cruiser lights. So even if drivers are distracted and glancing over to a GPS screen or cell phone they notice. Which is all I want. It works. A small price to pay for safety. I've got less than $50 worth of material in there and the total weight is around 1lbs due to a fairly large Li-Ion battery. That on is only large on the road bike, for 4-5h rides. -- Regards, Joerg http://www.analogconsultants.com/ |

Same if someone behind you flashes their headlights even while you aren't looking into the rear view mirror. Yet another one: Think about the reason why approaching emergency vehicles have very bright flashing lights. Now imagine all of these riders with lights and sirens: https://d3n8a8pro7vhmx.cloudfront.ne...png?1428427634 This is the daily commuter traffic into downtown. Now put all those people on the two-way cycle track on my way into work. https://bikeportland.org/wp-content/...ansit-bend.jpg Now live with that. As I've written several times, bright lights are not needed on bike paths. I turn them off there during the day. They are also not needed when there are lots of cyclists (safety in numbers). It's different out here, this is not Portland, Amsterdam or Copenhagen. Solid white lights in bright sunshine are almost universally irrelevant and annoying to other cyclists and drivers. No, they are not. Why do you think motorcycles have mandatory DRL? Just for fun? ... I see jerseys and body shape long before I register the light. That is totally contrary to my experience and that of just about anyone I know. ... And BTW, having driven ambulance for six years, I spent plenty of time sitting behind cars with my deafening Federal Q2B pegged before the dopey driver turned down the music and realized I was sitting there -- and then he freaks out, hits the gas, goes into the intersection and gets whacked. It can be a sh** show. Whatever giant light, siren, calliope, marching band you claim will save your life can only make a marginal improvement and proving that margin is hard if not impossible, and a blinding light can cause accidents or at least upset. That driver shouldn't have a license. What will really reduce accidents is being a good rider and knowing how to ride in traffic and with entering or exiting traffic. That's the problem. A lot of car drivers do not fall into that category and that is beyond my influence. What I can influence is how my ship is lit, so I do that. No you can't. Marine vessels must adhere to very stringent international regulations for the lights that they display and the brightness of those lights. I tend not to operate marine vessels on roads and bike paths. They'd get scraped up too badly :-) [...] -- Regards, Joerg http://www.analogconsultants.com/ |

Then why are you telling us the motorcycle story if it is not to illustrate that bright DRLs are needed? If you just want to talk about assholes in cars or motorcycles, that is rather mundane and has nothing to do with lights. sigh I bring these examples to show just _who_ is on such roads. Drivers that are reckless, inattentive, incompetent, slow in reaction speed, soused, stoned, or all of the above. And your post about being seen by on-coming, passing cars on straight stretches, you seem to confuse being seen with playing chicken. I ride on country roads all the time where cars in on-coming traffic get into my lane to pass. They can see me. I'm looking right at them. They just don't care. Being that I'm not riding a 3 ton F350, I pull to the right. A magical light doesn't change that dynamic. It does because I notice that with the light on fewer people attempt such maneuvers. I did a short ride today -- my legs are killing me, and I haven't been off my bike for weeks. It's overcast and rained this morning. I saw maybe thirty other cyclists on my little climbing route -- maybe two with DRLs. No deaths to report. No breathless hysterics, stranded people, incompetents with exploded tubeless tires. Totally normal, at least by Portland standards, which for you might be super scary since I'm riding on city streets at full speed! Eeek! I hear a lot of cyclists saying the legs hurt. For me it's never the legs, those are always fine. I run out of breath and become generally exhausted on long hilly rides. My legs could go on another 50mi but the rest of my body doesn't want to. -- Regards, Joerg http://www.analogconsultants.com/ |

I've been breaking and repairing things since I was an infant. At first, I would take something apart to see what was inside, and my father would patiently fix it, with me watching and learning how it's done. One day, when I was about 13 years old, I took apart an antique wind up clock and managed to release the main spring. Instead of fixing it for me, I was ordered to spend about 30 minutes per evening learning to fix the clock while my father watched and helped. I did my best but admittedly did it badly. I also noticed that my father was sitting on his hands while watching me work. He later explained that was to keep from strangling me as I made mistake after mistake. Having fixed cars, TV's, radios, mowers, phones, etc during the 1960's, I would say they somewhat easier than today's devices only in that the parts are larger and easier to see, and that the theory of operation was much simpler.

To balance that, the amount of information, videos, parts, and such available today is far more detailed and extensive compared to the Sam's Photofacts or the Sears parts catalog. Please find a better excuse for not taking a very simple bicycle headlight apart. My granddad had a professional repair shop, not like my cloak-and-dagger stuff. At this shop, they did absolutely *everything*. Bikes, cars, boats, radios, phones, TVs, you name it. Good luck finding such a shop today with a couple of guys being able to do all that with the usual set of everyday tools and a very small set of machines. Actually, I know of several. However, they don't deal with literally everything that walks in the front door. They work out of their garages and tend to specialize in various areas. Within the general area where I live, we have repair "shops" for string instruments, music keyboards, computahs, machine tools, bicycles, mechanical clocks, etc. They're still around, but because the cost of maintaining a walk-in store front and hiring employees is so high, they work out of their houses. For myself, I can usually diagnose most anything but have some difficulties fixing them. Last week was typical with the usual computer problems, but also several smartphone setups, three VoIP desk phones, an LCD monitor, a neighbors starter motor, dead battery in a customers car, plug a flat tire in the building managers car, LiIon battery charger repair, weather station (not fixed), AIO laser printer teardown to fix a gear jam, two router firmware upgrades, reset and reprogram a Roku media player, etc. This is typical for about one week. Most important tools used were my brain and Google search. Is have visited this shop and organized it, cleaned every tool, thrown away garbage, and all. What remains is good stuff, but still just the common stuff. Except for the electronics stuff, which I know nothing about, we had pretty much the same gear, him and I. The only thing he had that I didn't were a bunch of impact drivers. Other that that there were just sockets, combination spanners, different types of hammers, and so on. And with this, he solved problems in a range that's unthinkable today. Nice. There's another difference. He had years of experience, while you seem to be limiting yourself to what you can learn from a garage full of old bicycles and parts. That works, to a point, but I think you will do much better either working for someone else in order to learn the trade, or working on a better class of bicycle. For bicycle lighting, there is a difference between cheap junk and a light designed specifically for a type of bicycle riding. Or, perhaps building a clone of a high end bicycle light might be ummm... enlightening. You can buy all the components on eBay. Never mind what it looks like, build it in a wooden box. All you care about is how the light works and how long it will run on your selected battery. You'll learn quite a bit about electronics doing the calculations, building the light, and measuring the results. In order to buy the optics, you'll need to understand lumens, lux, and candelas, which should be a suitable incentive. Also, one other minor thing. When someone takes the time to explain how something works, I suggest you not repackage what they provided and ask them if that's is what they meant. Doing that is a trick that students sometimes do to reverse the situation on their instructors. Instead of the instructor asking questions, and the student providing an explanation or answer, the student ask the instructor the same question repackaged, and in effect tests if the instructor understands the question. The process does not demonstrate that you've learned anything more than rearranging a question. If you want to test your understanding, contrive a real life and very different situation involving the same principles and then ask if you are doing the calculations correctly.

This obsession towards building "the best bike light ever" doesn't help him much when he has to deal with dissatisfied customers who don't share his vision. From a business point of view, the non-intuitive truth is that Barry could probably achieve higher market penetration by selling out to a company that actually cares less about high quality bicycle lighting. |

Simple: 1. It prevents a large vehicle driver from overtake another large vehicle and then the driver seeing the cyclist when it's too late. I have other ways of preventing that horrible, tragic event. One of them is riding in the real world, not the fantasy "worst case scenario" world. It's not that I've _never_ had an oncoming motorist pull out to pass. It has happened perhaps two times in over 40 years of riding. And I've never had to leave the pavement to avoid tragedy. Hell, I've never even had to move onto the shoulder. 2. It causes oncoming motorists to see the cyclist much earlier and, for example, if a big semi comes they can pull a bit to the right so the semi can give the cyclist wide berth. I do NOT believe any practical light allows a motorist to see a cyclist _much_ earlier. In almost every case, I've seen on-road cyclists before I noticed that they had a light. And in no case did I see the light early enough to make any practical difference. You're fixating on a superstitious talisman, imagining benefits that don't exist in real life. -- - Frank Krygowski |

That's been said of bike helmets, hi-viz clothing, daytime running lights, air horns on bikes, six-foot tall flippy flags, lateral flippy flags, leg lights, laser-projected bike lane markings, elbow pads and knee pads, bike turn signals and more. Meanwhile, study after study has shown that the benefits of bicyclng greatly outweigh its tiny risks. IOW, riding a bike is literally safer than NOT riding a bike. I wish you'd switch to burdening pedestrians with your crazy "safety" ideas. 4500 fatalities per year. Something must be done! And you can make a profit by selling them junk! -- - Frank Krygowski |

It's a paranoia. Simple: 1. It prevents a large vehicle driver from overtake another large vehicle and then the driver seeing the cyclist when it's too late. I have other ways of preventing that horrible, tragic event. One of them is riding in the real world, not the fantasy "worst case scenario" world. It's not that I've _never_ had an oncoming motorist pull out to pass. It has happened perhaps two times in over 40 years of riding. And I've never had to leave the pavement to avoid tragedy.

And in no case did I see the light early enough to make any practical difference. You're fixating on a superstitious talisman, imagining benefits that don't exist in real life. The dopey part is thinking that motorists behave badly because they don't see cyclists. When a car right hooks you after passing on a bright sunny day, it's not because the motorist didn't see you. It's because he or she is an asshole. Buses and trucks pass me too closely all the time and not because they can't see me. On coming cars get into my lane to pass, and I know they see me because I'm glowering at them. I make eye contact. What I need is a handgun and not a bright light. Joerg believes that a bright light on a sunny day not only increases his conspicuity -- which it might, but probably not in any meaningful way -- but produces freakish compliance and passivity from motorists. Semi drivers pull right to give him more room in the opposite lane (which they wouldn't do for a car with its lights on) and oncoming cars refrain from passing. None of this behavior -- if it occurs -- can possibly be tied to having a bicycle light on a sunny day, at least not without stopping the semi-driver or car-that-didn't-pass and asking them why they did what they did when they did it. I know that bad behavior is not eliminated by bright lights because I get plenty of it with my lights on. And on top of that, there is the usual confirmation bias. I was riding yesterday in overcast after a downpour. I had cars entering from the right -- I got out in the lane in my fluorescent Gabba jacket, and the cars didn't pull out. I know for certain that it was because of my jacket. How could you not see that jacket -- it's like a yellow-green road flare. OTOH, the motorists may have seen a 6'3" 200lb guy on a bike who was riding in the middle of the lane in adequate light to be easily seen. But being that I own the jacket, I'll claim it saved me. I also had a front headlight, but it wasn't on. I've decided to take a day off. I'm going for a walk with my wife. -- Jay Beattie. |
