  1. So, I'm driving down a country road last night, and as I come around a
    corner a wildly flashing white strobe light accosts me coming the
    other way (fortunately on the opposite side of the road).

    My first thought was WTF? Then I realized it was a bicycle headlight,
    and my second thought was WTF!

    but did it attract your attention? or were you too busy trying to
    calculate your intersection coordinates to stay out of its way?

    The purpose of bicycle lights is not to actively attract attention (and/
    or confusion, distraction, irritation, etc.) The purpose of bicycle
    lights is to make the bicycle *visible* in conditions where it would
    otherwise not be seen.

    For this reason it is illegal in many (European) countries to have
    blinking lights on a bicycle. Blinking lights in these countries are
    understood to be indicators or signaling/emergency lights. I think the
    police here (Netherlands) would certainly frown upon stroboscopic lights.

    What's the difference between attracting attention and making something
    visible? Seems to me that if a bike light reaches the level of being
    consciously perceived it has done both. Anything that makes a cyclist
    sharing the roadways with motorized vehicles more immediately perceptible
    among the cacophony of distractions many drivers choose to surround
    themselves with these days is a good thing. Personally, I WANT to
    successfully compete for drivers' attention with their in-car TVs,
    cell-phones, food items they are stuffing themselves with as they drive,
    fighting kids in the back seat, etc.

    So, I wear bright clothing, put reflective items on the bike and myself,
    run a red strobe as well as blinking LEDs on the back, have two CCF light
    tubes on the seat stays, and use a powerful dual-beam headlight. People I
    know who happen to pass me in their cars tell me later, "I saw you on the
    way to work today." That's exactly what I want - to be easily seen. Use
    your faint steady lights if you choose to, but you probably won't have a
    chance to change your mind if you get hit. The purpose of bicycle lights is
    to keep you alive.

    BTW, the state patrol officers who regularly pass me on the highway NEVER
    bother me about my lights. They understand what I'm trying to do. They
    know how inattentive many drivers are.

    Some lights have a setting for this; the Cateye EL-410 is one.

    Silly me, I always thought that the purpose of a headlight was to, you
    know, illuminate the roadway ahead of the bicycle, and a strobe effect
    would have little benefit. In the midwestern US I rarely see people
    riding with blinking headlights.

    i think the more important question is not about a law dating back from
    whenever

    In the case of the Dutch Voertuigreglement ("vehicle regulations"😉, that
    would be 1994 (last updated).

    Like police everywhere: when they feel like it. They certainly have the
    right to do so.

    Quoted message said:

    I was ticketed once for not having lights at all. I know people get
    ticketed sometimes for having blinkers. But police officers sometimes
    seem to feel "well at least he has SOMETHING that looks like a light".
    They will tell you then to push the little button so it stops blinking
    and starts emitting light continuously. You will be educated on the
    requirements of the law and then sent off.

    Having normal non-blinking lights is still the norm that most people
    comply with. New bicycles (roadsters, not race/mountain bikes) will have
    good functional lights on them almost without exception. OTOH cheap
    blinkers are no longer rare since you can buy them at almost every
    supermarket. Many people don't seem to be aware that they are illegal
    when used in blinking mode. Many of them have unfortunately bought into
    the silly misconception that blinkers are "better" or "saver".

    They are not.

    Are you sure that's the reason they're illegal? I thought (based on
    rumour and conjecture) they were illegal in GB because of the absurd
    consideration that you are technically riding with no rear light at all
    for the duration of each blink's off-phase.

    I think they've changed the law here and they aren't illegal any more.

    Irrationality does find its way into legislation sometimes.

  10. I saw ONE also. VERY impressive rear red strobe. outstanding survival
    value for the oncoming drunken SUV. Police cheapo is online at $25-30.
    Master mechanic suggests strobe bulbs are more delicate than bike
    lamps or bike LED.

    From watching once, considering the police model or two as the colors


    are optional, is/as standard equipment for cross country touring or HD
    commuting.

  11. Another approach:
    I bought one unknown quantity>
    http://www.rei.com/product/723347
    the unit doesn't flash! Sheeeet. So I set it on and outside, walked
    back in and looked out thru the slider and it flashed. Yaaahhaaaa!
    Light flashes switchless as the kayak rises, falls and jiggles thru a
    jiggle lens.

  12. Red blinking lights are rarely (at least here in "the States"😉 used as a
    caution or warning blinker. Road hazards are marked with yellow or amber
    flashers, Police use blue, Fire uses red but it's always mounted on the
    top of the truck, and accompanied by a siren.

    The only time you see a red flasher at road level is for a stopped or
    slow moving vehicle that may pose a hazard to passing motorists. Since a
    bicycle is a slow moving vehicle that may pose a hazard, I think it
    qualifies.

    Surely you're not serious!

    Doubtlessly, lives have been lost in the blink of an eye. But I
    really doubt any life ever been lost because a motorist saw a
    cyclist's light blink, and blink, and blink, and blink... and then
    suddenly thought "Oh, it's been dark for half a second. That
    bicyclist must have vanished!"

    In some situations, there *might* not be enough time or opportunity to
    see the blink-blink-blink happening before one hits the cyclist.

    There are standards that lights are required to meet, and those didn't
    allow for flashing. I don't think it was because a flashing light is
    only a light half the time so much as they weren't considered at all. Or
    it could be that flashing lights were only allowed in certain
    circumstances, eg by emergency services.

    The highway code has been updated to allow flashing lights.
    http://www.ctc.org.uk/DesktopDefault.aspx?TabID=4568

    I think that bicycles (and trikes) are the only vehicles allowed to use
    blinkies as their only lights. Emergency vehicles have flashing lights
    of course, but these are in addition to the lights they are required to
    have.

    Four pedal reflectors are required too, and must be "plainly visible".
    This doesn't make a lot of sense with panniers or especially a
    recumbent. It makes almost all clipless pedals illegal, and selling a
    bike fitted with them also illegal, but no one seems to care.

    So much for .uk on to the country I live in now. In .nz I think there
    was a prosecution several years ago against a cyclist who had a blinkie.
    Flashing red (and/or blue) lights were only legal for emergency
    services, but I don't know how the case turned out and suspect it got
    dropped. It was several years ago, so I could be misremembering, and I
    can't find anything on the web that refers to it. The law was changed to
    allow blinkies.

    We are allowed either steady or flashing lights, but if there are two at
    the front only one can flash. Lights are required at night, of course.

    Pedal reflectors or reflectorised clothing/straps on the lower leg are
    also required. This gets ignored a lot.

    My Japanese sources say red flashers are reserved for emergency
    vehicles, hence no bike flashers there. A quick reading of US statutes
    might make that a grey area here, too. In practice, cops seem to find
    other activities to fill a shift besides writing cyclists for the
    'wrong' kind of bike light.

    It's a gray area. Flashing yellow lights are legal for warning about
    "slow moving vehicles." Flashing red lights are legal in some states for
    bicycles.

    I find the flashing white lights on the front of bicycles to be mildly
    annoying, but very visible.

    Well, the one I posted about was way past "blink" and into "bright
    white strobe headlight". I think it represented more of a hazard to
    motorists than it did a safety device to bikers, at least on that dark
    country road. Not to mention, as the bike's apparent headlight, one
    has to assume the rider gets an interesting view of the road in front
    of him.

    I think it would be a "feature" if it was a small add on light
    designed to draw some attention beyond that of the usual steady
    headlight, but as a primary headlight, it was not a good thing.

    I'm still skeptical. That would have to be limited to situations
    where the cyclist came into the visual field only a second or so
    before the crash.

    Yes, to me, anything as blinding as a strobe is mindless overkill.

    ISTM that a blinking front LED in _addition_ to a proper steady
    headlight, could add a modest bit of benefit. The effect would be
    very similar to the modulated headlights used by some motorcyclists.

    However, I'd stop way short of saying they're necessary on a bicycle -
    which is where a lot of people seem to end up, when praising their
    personal choice of safety equipment.

    There's not at all illegal in the UK.

    What is required is that you DO have a legal set of lights. Extra lights
    are fine - as long as you also have the legal ones.

    I haven't seen Ben C's or nmp's posts. Perhaps they weren't x-posted to
    urc. But no, flashing lights are no longer illegal in the UK, even as a
    primary light:
    <http://www.opsi.gov.uk/si/si2005/20052559.htm>

    (FWIW I don't approve of this change in the law. I'm happy for flashing
    rear lights to be legal, but not flashing front lights nor for any
    flashing light to be legal without having a steady light alongside it).

    The flashing rate is limited to 4 flashes per second, presumably to
    prevent any possibility of a flashing light triggering an epileptic fit.
