    That's interesting... How severe was the snippage? This would make
    common turn signals illegal (flashing light) and the common amber turn
    signal doubly so (flashing and not red in the rear).

    Take a peek:
    http://www.legis.state.wi.us/statutes/Stat0347.pdf

    Most US state statutes are similar

    Section 347.489, which deals specifically with bicycle lighting,
    contradicts the general rule:

    "A lamp emitting a red or flashing amber light visible from a distance of 500 feet
    to the rear may be used in addition to but not in lieu of the red
    reflector."

    In a case like this, a court would probably say that the specific rule
    trumps the general rule when it comes to bicycles and thus allow a rear
    flashing amber light. Or maybe not.

    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!

    I just bought the lightman xenon strobe, in comparison to the LED blinky i
    have from SIGMA it sucks...
    It has a white xenon strobe inside, with the clear cover it is very
    powerful, but it loses most of its power when you put the red cover on it!
    It is multidirectional but behind the strobe there is a miror that focuses
    the light forward, wich doenst make it more wide angeled than the sigma LED.
    The LED flashes rather fast and with almost no time between the flashes, you
    can look in to it and it captures attention verry well.
    The strobe flashes once per second, it catches less attention and your eyes
    can't look in to it, though it is not at all brighter than a LED.
    Good for emergency strobe, not at all good stuff on a bike!
    With the clear lens positioned to the front of the bike your eyes will have
    difficulties due to the extremes between the on and of moments.
    Then there are the bike mountings, not sturdy and they don't seem to be
    designed for the strobe, one screw that only just gets in the whole of the
    lightman and can not fix it as it should.

    This is why flashing lights for use on the front of the bike have a
    maximum brightness specification, and should not be used on their own
    in the dark. If the xenon strobe has a body mounting option, and is
    still waterproof without the red cover, I would attach it to your back
    for use as a supplementary beacon.

    I use photon or nashbar blinkie (s) in amber, 1/2x1" front and side.
    the NOTICE factor is so high, people comment on the lights as I ride
    thru.
    the fronts seperate the bike from a porch light.

    This is perhaps true where you ride, but not everywhere. Can you post a
    link to this specification please.

    AIUI in the UK flashing lights for both the front and rear have a
    minimum brightness of 4 candela. There is no maximum.
