Bike lights to BS
I've recently bought a Brompton bike for my weekday work commute in London.
I'm a bit confused about what constitutes the correct type of bike lights, that meet British Standards. Argos for instance selling all manner of LED bike lights, which as far as I can see aren't BS compliant ? ? So why bother stocking these, unless of course you want to compliment these with BS ones ? ? So, if I buy a set that aren't to BS - am I using my bike (after dark) illegally ? |

Argos for instance selling all manner of LED bike lights, which as far as I can see aren't BS compliant ? The law was changed last October and quite a lot of things that weren't kosher before are now. Flashing LEDs, for example. Though the law has changed I have no idea whether the BS has. So, if I buy a set that aren't to BS - am I using my bike (after dark) illegally ? Probably not now, and also the case that other EU legally compliant lamps may well act as a suitable Get Out Of Jail. Moving sideways from the actual legalities, if you want the cat's pyjamas of lighting for your Brom get a SON XS dynohub and then you'll always have your lights ready to go whenever you need them. Doesn't add too much weight, no noticable drag when in use and even less when it isn't, and no noise, slippage and engagement faffs as with "bottle" types running off the tyres. A SON isn't cheap, even less cheap when combined with similarly Top lamps, but I'ce no regrets from putting a dynohub on my Brom.

ISTR that you'd also be using it by day illegally!!! But most plod would take the view that any light is better than the usual non-light.... |

Doesn't add too much weight, no noticable drag when in use Do you SON owners who charge around at top speeds on your normal bikes choose an XS hub? I understand that the drag from them is lower. For someone who hardly ever rides at less than 20 km/h, would an SON XS on a normal-sized wheel supply enough power? Daniele |

I don't think you mean the XS. The XS is the extra-narrow SON for Bromptons which is marginally less efficient and wouldn't fit a normal hub anyway. For someone who hardly ever rides at less than 20 km/h, would an SON XS on a normal-sized wheel supply enough power? I think you are referring to the normal SON for wheels under 20". There's no inherent reason that couldn't work, but do you really never want to see where you're going when climbing hills? Also it would eliminate the possibility of twin headlights or the Solidlights brick. -- David Damerell Kill the tomato! Today is First Leicesterday, September. |

When overnighting with my Lumicycles I confess to switching the front lights off on the uphills (assuming no traffic, which is normal in the middle of the night in these parts) to conserve battery. -- (Simon Brooke) http://www.jasmine.org.uk/~simon/ Tony Blair's epitaph, #1: Tony Blair lies here.

You don't need much but with the 20" SON you'd get none in Cornwall-type terrain.

Part of the attraction of dynamos is not having to do that sort of thing. -- David Damerell Kill the tomato! Today is First Brieday, September. |
