Cheap bright tail light
Just got one of these:
http://www.fasttech.com/products/160...de-red-bicycle It is bright enough to leave retina spots. I am impressed for the $13 price. Now it's time to do some real world testing. Only nit: I would like a lower duty cycle flash for better battery life. It has a built-in lithium cell, I'm thinking of adding an external connection for a 18650 cell or pack. |

Let us know how it fares. I never had luck with these removeable slide-in holders. Eventually the lights fly off into the bushes, never to be found again. Ok, I am a mountain biker. On the last one I jammed a screw through there. Why doesn't anyone offer a decent light set where there actually is a 2nd wired connection at the battery pack and also one at the tail light? Why do bicyclists always have to kludge in order to get good stuff? Battery powered rear lights are adding risk to cycling. Because you may not notice when they run out of juice and then a car driver may not notice you ... -- Regards, Joerg http://www.analogconsultants.com/ |

Ones with a battery pack connection? Got an example? I have only seen motorcycle lamps like that and if needed I'll buy one. But that would require a 12V step-up converter which I have to build and which has to fit inside the light, plus roach in a switch somehow somewhere. -- Regards, Joerg http://www.analogconsultants.com/ |

In the days of light bulbs one could buy a sturdy metal-encased lamp that would last. Now one can't. That's the problem. The problem is that (at least in the U.S.) few people ride at night. People think it's hideously dangerous. And of course they all have cars. So the market is small. And most of those who do ride at night tend to do it pretty rarely, only in near-ideal conditions, because they're doing it only for fun. So they tend to be pretty easy on their equipment. If it lasts only 50 hours, they'll get perhaps ten years use out of it. Also, regarding one of your specific complaints, most people don't see a need to run wires from a central battery to a taillight. AA or AAA batteries in taillights last a long, long time and are easy to buy and change. The few of us that may be light connoisseurs often tend to be reasonably good mechanics and/or machinists. We make what we want. I've got totally custom headlight mounts on three bikes (varying degrees of sophistication), and somewhat customized ones on two others. With a collection of scrap metal, a vise and drill and maybe some taps, you can do a lot. -- - Frank Krygowski |

If it lasts only 50 hours, they'll get perhaps ten years use out of it. That is because hardly anyone commutes anymore which is sad. Serious commuting means including winter and then one or both trips will require lights. So 50 hours would be gone in a month or two. I run through batteries as if it was popcorn. Environmentally not so cool. Luckily the front one on the MTB is Li-Ion but one of them already starts to fade. Also, regarding one of your specific complaints, most people don't see a need to run wires from a central battery to a taillight. AA or AAA batteries in taillights last a long, long time and are easy to buy and change. You cannot get any serious light out of AAA and that's all you normally find. A 2W LED will suck AAA dry in very few hours. Cygolite has Li-Ion but then the light is in one of those chintzy snap holders so you can carry it inside to your computer. My last light with such a holder flew off half way into a ride. I heard it crash into the bush and it was gone for good. The few of us that may be light connoisseurs often tend to be reasonably good mechanics and/or machinists. We make what we want. I've got totally custom headlight mounts on three bikes (varying degrees of sophistication), and somewhat customized ones on two others. With a collection of scrap metal, a vise and drill and maybe some taps, you can do a lot. I guess that's what I'll have to do but first I'll visit the local motorcycle store because that industry is a tad better when it come to serious quality stuff. I don't mind making a light mount but I'd need some kind of light that I can securely attach to that and where bumping into it won't crack anything. Because on an MTB you must sometimes hover over the rear wheel and it's easy to bump into the tail light. Something like this with LEDs in there would be nice: http://www.amazon.com/Protective-Alu...QVDGNNEGG130D8 Many of the "modern" LED light for motorcycles are junk, just like those for bicycles. The good stuff would need to be retrofitted. -- Regards, Joerg http://www.analogconsultants.com/ |

Why, as this article states, http://www.slate.com/blogs/the_slate...t_popular.html "Bicycle Commuting Rates Rocket From 0.5 Percent to 0.6 Percent in Only 32 Years!" According to the League of American Bicyclist's usual modus operandi, that should be trumpeted as a 20% increase!!! ;-) Serious commuting means including winter and then one or both trips will require lights. So 50 hours would be gone in a month or two. I run through batteries as if it was popcorn. Environmentally not so cool. Luckily the front one on the MTB is Li-Ion but one of them already starts to fade. Yep. Another couple reasons to love generators or dynamos. They last damned near forever, and low temperatures don't bother them. Also, regarding one of your specific complaints, most people don't see a need to run wires from a central battery to a taillight. AA or AAA batteries in taillights last a long, long time and are easy to buy and change. You cannot get any serious light out of AAA and that's all you normally find. A 2W LED will suck AAA dry in very few hours. Do you really need 2 Watts into a rear red LED? Even bog standard red LEDs are pretty efficient, in terms of lumens per watt. And since you're moving with traffic, motorists generally have plenty of time to spot you. Everyone else has heard this from me before, but: I heartily recommend enlisting a helper, and observing your bike and it's nighttime equipment in your normal traffic conditions. Have your helper ride the bike, and drive past him from various directions. I've done this every once in a while since about 1978 or so. (Actually, in '78, I did the riding, my wife did the driving, and my son did the note taking.) I've also done it several times with bike club members, a couple times as a formal "night lighting workshop." I mention this because people have invariably learned that it doesn't require huge outputs of dollars or lumens to make a cyclist very conspicuous at night. Except for my now modern headlights, most of my night equipment is very ordinary, and there have been many times (at least six) that I've gotten spontaneous compliments from motorists, pedestrians, and other cyclists on how well my lights and reflectors show up. (And don't forget, reflectors and reflective tape can work very well - especially low on the bike, and on moving parts.) You should try testing your bike's lights that way. It may give you peace of mind. -- - Frank Krygowski |

According to the League of American Bicyclist's usual modus operandi, that should be trumpeted as a 20% increase!!! ;-) :-) But I do have to say that since they started putting in more bike paths and bike lanes it has picked up more than that here in the last 7-8 years. To the point where new bike dealers are opening while until 2005 they were dying left and right. I also see some more longhaul commuters in road bikes. What is sad is that some beautiful trails out here are barely used. When I see another montain biker there we great each other enthusiastically because that happens maybe once a month and I ride them 2-3 times a week.

It may give you peace of mind. On my road bike that's true. It is hugely decked out with reflectors and I don't need lots of lumens and the light does not have to be full metal or very sturdy. On the front I need something better though because I need to see farther out for top speed. On the MTB that's all different. No space for reflectors, everything I tried flew off. A small light gives inattentive drivers the impression that something is far away and I had a few close calls. I mostly like to be seen also during the day and I want my tail light to stand out from the crowd. So that despite it's small size people wake up and think "Whoa, there's something weird up there". I see that on county roads where bikers with really bright lights stand out. You see them from half a mile away and can easily prepare for the time you have to pass them. -- Regards, Joerg http://www.analogconsultants.com/ |
