  1. For urban riding, where the imperative is not so much to see the
    already-lit road at night but to be as visible as possible to other road
    users, is there any reason not to prefer LEDs over more traditional
    lights?

    Currently it is not legal to have only LED lights on bikes. Also you
    are obliged to have orange pedal reflectors and a BS red rear
    reflector. While LED lights are often brighter and more reliable than
    filament lamps, if you are in collision with another road user and try
    to claim for damages the other parties insurance company might argue
    for reduced damages as you were not legal with only LEDs. Thats the
    situation as I see it, I am not a legal expertise and don't have 100%
    legal illuminations on my bikes, but I believe I can be seen.

    For rear lights, no reason at all. Units like the Cateye AU100 are
    completely British Standard compliant and are fully legal (at least used
    in steady mode). The batteries last for ages and they're excellent,
    highly recommended.

    There are now BS compliant front LED units, such as the Cateye EL300.
    As well as things like this there are lesser lamps which are probably
    okay but may leave you in a legal hole if the worst comes to the worst.
    For urban riding I like to use dynamo lighting which is always there
    when I need it, legal and throws a good beam into the bargain.

    Couple of weeks ago I nearly missed seeing a cyclist with a blue/white
    flashing front light. the cyclist was a dark object against a dark
    background and the LEDs were weak. I've more expectation of being seen with
    my 20w/35w Lumicycle combo. I usually only switch the 35w on at roundabouts
    and junctions.

    I had a good look at the relevant standard (BS6102: Cycles, part 3:
    specification for photometric and physical requirements of lighting
    equipment, 1986) recently and it doesn't actually say *anything* about
    requiring non-LED light sources. It specifies minimum and maximum
    intensities at various points in the light beam, as well as all sorts of
    other things like resistance to water, salt spray and vibration, and
    battery life and labelling.

    There are LED lights which meet the standard: I know Cateye have some.
    There are also LED lights which are designed to meet the standard but
    haven't yet been through the expensive and time-consuming testing
    process. Modesty prevents me from mentioning them, though ;-)

    The law is that LED's are not non-lawfull per-sae but that flashing LED's
    are non-lawful. I would say that some cheaper LED's have the same power
    as half a glow worm so make sure you get one which has some power to it.
    I use a 5 bulb LED tourch now over my old maglight, it's just as
    powerfull, in fact more so and less than a third of the size and weight
    plus the batteries last 500+ hours rather than 8'ish.
    Relevant rules would be in the "Road vehicles Lighting Regulations"

    Statutory Instrument 1989 No. 1796
    The Road Vehicles Lighting Regulations 1989 - continued
    <Snip>
    Lamps to show a steady light
    13.?(1) Save as provided in paragraph (2), no vehicle shall be
    fitted with a lamp which automatically emits a flashing light."

    I find it very difficult to judge how far away a cyclist is (whether i am on
    bike or in car) when all they show is a flashing light. But a steady light
    can get lost in a busy street scence

    FlASHING = better visibility

    STEADY = better distance estimate.

    I prefer a combination of flashing and steady.

    All of my lights are now leds which I run with rechargeable NiMH cells.
    Very reliable and highly visible.
    I use all these these 4 lights on my hybrid bike. Two flashing and two
    steady.

    I stand corrected, thanks, its good news IHMO. I had heard something
    different recently.

    The BS which is written into law is not the most recent revision of
    the BS in question.

    I believe it specifies filament bulbs, and I believe it does so
    because they wanted to disallow oil/parafin/whatever lamps, or that
    other one where you drip water onto something and if it doesn't
    explode you can burn teh gas produced.

    Quoted message said:

    Cateye's BS lights don't meet the legal BS. Also (incidentally) if
    you fit them using the bracket that comes in teh packet, they don't
    even meet the BS they could meet (though you can buy a mounting
    bracket that does meet the BS as an optional extra).

    Back to teh original question, I believe you can be legal with LED
    lights because you're legal if you use lights that meet an equivalent
    standard for use in another EC country. Germany has a standard which
    can be satisfied with LED lights (and I have a set meeting teh German
    standard on my commuter).

    The law specifies an earlier revision of the BS.

    Also the bracket this lamp is sold with does not meet the BS, so
    unless you bought an extra mounting bracket for it, it doesn't even
    meet the BS it claims to (it tells you this in small print)

    I think Martin's comments are based on the fact that the relevant
    lighting regs used to refer to a specific revision of BS6102 which did
    not allow for LEDs (long after the /current/ BS6102/3 did allow them.
    I am not certain if this is still the case (I have a feeling it isn't
    due to some sort of EU regs harmonisation). The point Martin was
    making was that it is the certification that is important, not whether
    your lamps meet the standard

    That's very interesting: I didn't know that the standard and the law
    were two such different things. Roll on harmonisation, I say.

    I do remember an older version of the BS standard which basically just
    had pictures of the old (n)Ever Ready front and rear lights and said
    "they must be like this"!

    Yes, it's a question as to whether or not they got through or not. I know
    there was a consultation document in which the proposal was made that the
    rules relating to LED and flashing lights was put forward and an
    ammendement tabled but if this came into force or not I am, as yourself,
    sure. There was a statement that the lights must/should be BS6102 or
    equivalant which as you also say would allow lights of similar standard
    with EU or other testing systems as 'legal' within the UK.
    The question is not so much the power output of the light as I understand
    it but the flashing nature of the light which as far as I can ascertain
    has not been repealed or ammended. Frankly as a police officer I don't
    give a tuppeny chew if the light is flashing or not, so long as it's there
    and visible.
    I also recall something about the DFT putting out conflicting statements
    about the legality of the lights against filiment bulbs one saying they
    were legal and another they were not, from memory this was way back in
    1996.
