dynamo lights with switches and bottle dynamo/generators
Hi all,
I want to know if you can use a bottle dynamo with a light with a switch? My guess is no given that the switchable examples are usually in the hub dynamo section but I don't understand why this is the case? Couldn't I by a switchable light and just leave it in the on position with my bottle dynamo? If not, why not? Thanks |

I bought a '3 - way' switch and had a couple of AA batteries, set up so that when I needed to stop, I could flip the switch from the generator position to the battery position and, therefore, still be adequately visible.

Cheaper without the switch normally, though if you're planning a hub upgrade at some point that's not relevant. |

A switch is an extra feature adding cost, since the bottle dynamo itself already is a switch to activate light.

Yes, could see there's a premium on the switchable models but also from what I read that they were only suitable for hub dynamos for some reason. Gladly not as I've been gifted one. Can you tell me if non-switchable models can be used with the hub generator then? Again, I don't see why not but ..... Obviously the light would always be on but no other reason? |

Cheers Helmut (Where do you stand on the Helmut, erm helmet debate?), Do you know if it's true the other way round? i.e. non-switchable models on hub generators? Obviously light is always on but there's no other current regulator or other electronic device built in to these switches? |

Obviously the light would always be on but no other reason? Well, if it was a filament lamp, bumb life may be an issue, and people might be put off by the slight increase in drag, but that's minimal, so there's no real other reason. |

The typical average lifetime of a halogen bulb is about 100h, for smooth roads, which is little. Unless you are running an LED based headlight with thousands of hours average lifetime it is a good idea to have a switch... Obviously light is always on but there's no other current regulator or other electronic device built in to these switches? For LED based lights you have electronics anyway, the switch typically is just a switch. -- MfG/Best regards helmut springer panta rhei |

Hi all, I want to know if you can use a bottle dynamo with a light with a switch? Of course you can. My guess is no given that the switchable examples are usually in the hub dynamo section but I don't understand why this is the case? Because otherwise the light will always be on. In the case of a bottle dynamo you switch the light by putting the bottle on the tire. Couldn't I by a switchable light and just leave it in the on position with my bottle dynamo? Yes or you can leave the bottle dynamo on the tire and switch the light with the light switch. ;-) Lou |

Quieter, which may be a feature. No technical difference between switching off the power or interrupting it. For that matter, no reason to turn a dynamo lamp off at all (mine are 'always on'). -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |
