Don't worry, this has got nothing to do with any other recent threads on bike lights.
It's something I've wondered for a while, then that thread about police officers getting injured at work and the way insurance companies will always try to get out of paying brought it up again.
I can remember the old 6v "tin can" lights, Ever Ready or Pifco I think, usually mounted on a bracket half way up the fork leg.
They were next to useless, but I'm fairly sure they used to carry a British Standards Kite Mark.
As far as I know, none of the modern type of LED front lights carries a BSI or CE marking.
Is there a legal standard ?
If a cyclist got hit by a car at night, could the car drivers insurance company get out of paying because the bike didn't have CE approved lights ?
All motor vehicle bulbs, lights, reflectors and lenses are CE marked, as are reflective jackets for road workers.
Is there no similar standard for bike lights ?
On a similar subject, I remember being told by a bike shop owner, years ago in the days of 1.5v bulbs and D cells, that he wasn't allowed to sell rechargeable batteries in a bike shop, because of the way they went flat.
Standard batteries faded away over an hour or so, rechargeables went from bright to flat within minutes, supposedly catching cyclists by surprise and leaving them with no lights.
There was nothing to stop me going next door to the model shop to buy rechargeable batteries and putting them in my lights myself, but he wasn't allowed to sell them to me.
Is that true ? And if so, does that law still stand ? How does that affect modern rechargeable Lithium Ion batteries ?
