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 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. A really bright light is required to make much difference in that case. 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. Yet another one: Think about the reason why approaching emergency vehicles have very bright flashing lights. In my world they usually turn on their sirens when approaching busy intersections, especially if they intend to blow the light. There is a reason why DRL have been mandatory on US motorcycles for a long time. -- |

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. Solid white lights in bright sunshine are almost universally irrelevant and annoying to other cyclists and drivers. I see jerseys and body shape long before I register the light. 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. What will really reduce accidents is being a good rider and knowing how to ride in traffic and with entering or exiting traffic. A DRL may help, but it is certainly not magical and is irrelevant in many situations. Lights are critical at night, obviously -- but mega lights are totally unnecessary on city streets in dry weather. What is "enough" at night varies depending on terrain, conditions, etc., but whatever is enough, it can't be blinding people. -- Jay Beattie. |

Whether or not you notice them or not depends largely on how bright they are. With the usual rather dim warning lights you don't, or at least normal people don't notice them until their eyes happen to look at the dash. As for someone behind you flashing their lights, again it depends on how close they are to your car. A distance behind you and normal people don't notice at all, but of course if they are close enough that their lights are illuminating the whole inside of your car and you have to squint in order to see the road you will notice. Yet another one: Think about the reason why approaching emergency vehicles have very bright flashing lights. There is a reason why DRL have been mandatory on US motorcycles for a long time. -- Cheers, John B. |
