A Non-friction bicycle lights generator (dynamo)
In this new generation bicycle light system, no battery is needed, no
friction on any parts of the bicycle. The lights flash regardless speed of the bicycle and weather conditions (unlike normal dynamos!). Very bright. It can be used as a stand-alone light system (as a normal dynamo) on your bike, or used as a back-up for your existed battery-powered lights. There are DIY kits of this dynamo. All details and buy on-line: http://www.freelights.co.uk |

Probably yes, if you referto the flashing ness of the lights, there has been a recent change in the law that allows cyclists to have flashing lights on their bike -- Chris French |

Flashing lights may be used, but they *MUST NOT* be used on their own, a normal *constant* output light source must be used as well. |

5 leds means very little light. It probably works but is crap. No
resistance is impossible - very little resistance means very little light. You don't get owt fer nowt, cheers Jacob |

As long as the lights put out at least 4 candela it's legal Wrong. Sorry, but you are the one who is wrong, though it is a recent change in the law so I'll let you off.... Try reading the relevant law relating to this, (RVLR regs 18 £ 24), May I suggest you do the same. I refer you to 'The Road Vehicles Lighting (Amendment) Regulations 2005' http://www.opsi.gov.uk/si/si2005/20052559.htm Which came into force 21/10/05. rather than what the ignoranus fascist cyclists try and suggest. This cyclist isn't ignorant or fascist, but he does know what the law is regarding cycle lighting. If you are going to throw out stupid insults it pays to be sure of your ground first. Flashing lights may be used, Actually it was illegal to fit flashing lights to cycles under the previous regulations (though legal for the cyclist to wear them). but they *MUST NOT* be used on their own, a normal *constant* output light source must be used as well. The above Amendment to the RVLR now makes flashing lights BY THEMSELVES legal on cycles. At the moment the only requirements are that the flashing lights have brightness of at least 4 candela and flash evenly between 1 and 4 times second. This is probably an interim measure, and presumably BS6102/3 will be amended in do course (there are oddities, like if the light has steady mode it must meet the more stringent requirements of BS6102/3) http://www.ctc.org.uk/DesktopDefault.aspx?TabID=4071 Seems to give a good summary of the current law re cycle lighting regulations whether or not the light in question that started this thread meets the requirements I've no idea, I can imagine it may well not. -- Chris French |

My point is that if it is deemed unsafe to have a rear light below a certain wattage on a car why wasn't the _same_ legislation applied to bicycle lights? The legislation with regards bicycle lighting was probably written around what was practical at the time. Technology has since improved and the better quality flashing lights allows the bicycle rider to be more noticeable to other road users. The biggest problem is that the majority of bicycle riders don't fit any form of lighting when riding at night. Road safety is probably not compromised at all by fitting flashing lights rather than constant lighting, but it is by not fitting any lights at all. -- Alan |

You'll also notice that the "exceptional" vehicles that may cause an additional hazard (stopping in odd places, not following normal rules of the road) are fitted with flashing orange or blue lights. Err, blue lights are only fitted to emergency vehicles (and are in addition to other lighting), as for flashing amber lights (which are again in *addition* to the normal regulatory lights), if you are suggesting that cyclist should be made to fit or wear them as well [1] - you might have a point, I totally agree, many cyclists are nothing but mobile hazards! [1] I can just see a market for cycle helmets with built-in flashing amber bacons... :~) |

You could see the lamps flicker as they turned :-) Bottom-bracket mounted dynamos are pretty good as they don't scrub like the sidewall-driven ones can, but they can be prone to slipping and/or rapid wear because the back tyre dumps loads of crap on them.
