I've never heard of such a case. I think it's yet another exaggerated danger. Bicycle lighting seems to be divided into "see where your going" and "be seen" parts. Standlights are in the "be seen" part. If so, then using a relatively narrow forward facing headlight is inadequate and a poor substitute for all around "be seen" type lighting. So far, no driver has tried to kill me while I'm stationary, but it's possible. To help prevent such a threat, I would need all around illumination because I don't know from what direction the driver might approach and I do NOT need to see where I'm going (because I'm not going anywhere). Some kind of flashing headband, flashing arm bands, or maybe downward facing flood lights to illuminate an area. Maybe an LED illuminated vest, which is now popular among highway workers: https://www.amazon.com/HIGH-VISIBILITY-VEST-COMPLIANT-REFLECTIVE/dp/B01L2US0EY https://www.amazon.com/SE-EP08L-Illuminated-Flashing-Feature/dp/B008WAE2XQ https://www.amazon.com/SE-EP07L-Flashing-Illuminated-Safety/dp/B004J663A2 I don't know which type of "be seen" lighting might be most effective, but any of the aformentioned would be better than a dim forward facing standlight. Thing is, nobody's demonstrated any need for so much stationary "be seen" light, beyond the usual "well, it _could_ happen" safety inflation mentality. We're facing the same mentality regarding our local forest preserve. Some people want to cut down every dead or dying tree within 100 feet of any trail because, well, it _could_ fall on somebody and kill them. Sheesh. -- - Frank Krygowski I remember the Soubitez (sp?) ads from the 1980s that showed a stopped bicycle without a front light at an intersection at night and another image of the Soubitez dynamo light with the standlight. The ad was about how much safer yuo were with the Soubitez dynamo because others could see the light whilst you were stopped or just starting up again. So this perceived need for a safety standlight on a dynamo powered light is nothing new. As I recall, that system failed in the marketplace. The idea might have existed in a few minds back then, but it wasn't common enough to be commercially successful. The same could be said of many present "safety" devices. You'd have gone broke trying to sell "walker safety vests" in the 1970s or 1980s. Ditto little hammers to let you break your car window if you were trapped inside. Or foam pads to put on the corner of every hard object your toddler might walk by. Or bathtub mats that say "HOT" when the water is, well, hot. But all those things have been sold recently. None anywhere near as lucrative as Pet Rocks (a product of similar utility but more trendy) Regarding Soubitez standlights of the 1980s, devastatingly unpopular. http://www.yellowjersey.org/photosfr...t/soustan1.jpg http://www.yellowjersey.org/photosfr...t/soustan2.jpg -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |
