Light for commuting
Help.
I need a decent front light for commuting. How hard can it be to find a light that is: * Rechargeable * Powerful - 12 W or more would be nice * Robust * A single unit that snaps onto a bracket and can easily be removed when I park the bike - those bottle battery thingies are way too fiddly for utility cycling. I don't care if it's bulky. * WIDE ANGLE - directional lights are useless on lit roads. I don't care about seing. I only want to be seen. I've looked everywhere, but coudn't find anything even closely fulfilling the above. Do you know if such a light exists somewhere? One of these days I'll build it myself... |

One of the compact bright LED lights is more than enough and the batteries will last for ages.

If you search on e-bay you can find the powerful cateye lamps from the USA for about half the UK price (including the postage). They're bright. |

Are you sure it's bright enough?
Basically, I want to make sure I'm at least as bright as a car headlight so I stand out from the rest of the motorised traffic. The type of model you're suggesting is quite a lot weaker in my opinion. Also, they're a bit flimsy and get damaged easily. |

That LED stands out in motor traffic in a way that a halogen light can't. The brightness and the colour hue set it apart from the mass of halogen lights around you. I've not managed to damage one in two years of commuting. -- Tony "The best way I know of to win an argument is to start by being in the right." - Lord Hailsham |

You aren't going to get that. The motor car has a tens of horsepower engine continually maintaining the charge in a tens of amp-hour battery weighing tens of kilogrammes. You don't have that engine, and you don't have the carrying capacity for that battery, so you can't drive a light of that intensity for any length of time - even very expensive technology such as HID lamps and lithium ion batteries will only give you 'the equivalent of 40 watts' when standard car headlamps are 55 watts and more and more upmarket cars are already using similar high brightness technologies. In any case it's not a solution. In the arms race of headlamp intensity we all lose: a light for a light leaves everybody blind. What you need to be is distinctive and recognisably different. In urban conditions on well lit streets I would suggest this means a combination of the bright flashing LED lights which have recently become legal and at least one reasonably bright steady light - either an LED or a dynamo-powered light. -- (Simon Brooke) http://www.jasmine.org.uk/~simon/ ;; L'etat c'est moi -- Louis XVI ;; I... we... the Government -- Tony Blair |

Are you sure it's bright enough? I second Tony's recommendation for the Smart Polaris. I do have much much more powerful lights in addition that I bought for unlit country roads but I usually have them switched off when I'm on decently-lit roads to conserve battery. Despite its diminutive dimensions, I'm that confident that I can be seen with the Polaris. However there are bigger brighter LED lights if you want one -- loads on the market, flashing and steady ones (note most flashing ones have a steady mode too). Certainly some sort of LED type will be best for you if you don't want a light for seeing where you're going. Basically, I want to make sure I'm at least as bright as a car headlight so I stand out from the rest of the motorised traffic. The type of model you're suggesting is quite a lot weaker in my opinion. I don't think you can't compete with car headlights in that way without having the type of battery you don't like. As Tony says, a flashing light makes you stand out. Actually I think just being resonably visible and being careful is sufficient to be safe. Remember the "risk compensation" factor. If you think you are extremely easy to see then you will take more risks. Despite my best intentions, to be honest I find myself speeding though junctions faster when I have my big "f*ck off" light on. If I'm wrong and someone waiting to turn right doesn't see me afterall then I'm in big trouble. Better to assume you're invisible until you get some sort of indication that you've probably been seen. Also, they're a bit flimsy and get damaged easily. This particular one isn't. The bracket is nice and reliable and the light survives being dropped on the road. It also makes a handy emergency torch (that's when I've dropped mine). Ironically, more powerful lights can easily be more flimsy. ~PB |

On my theory from stopping helmet wearing that emphasising you are a person on the bike, the backwards light changes you from a headlight to a very visible person in traffic and seems to make a big difference in drivers noticing you in the dark. As long as it is shielded so it doesn't shine in your eyes it works a treat. -- Tony "The best way I know of to win an argument is to start by being in the right." - Lord Hailsham |

A think you are only allowed a maximum of n-1, where n is the number of requirements above. I would strongly recommend the Light and Motion Vega as a commuter light.

And the sheilding would have to be very good indeed if you ride on completely unlit roads. ...d |
