A company named  OccuNomix Int. Inc. markets a flashing safety armband
made from an electroluminescent strip powered by 2 AAA bats. that
operates for more than 225 hours and is visible up to 5000 ft.. The
light is yellow-green. I bought mine from a safety catalogue. They are
advertised as being useful for road construction workers. I contacted
the co. and asked if they would be interested in retooling the battery
case to be sumersible rather than water resistant. I mentioned that
there could be a market for sea kayakers and they wrote back that they
werent interested in redesigning their product. This technology could be
easily incorporated right into a PFD or helmet or even a hat or the boat
itself. Anyone interested in tinkering with this can contact
occnomix_at_aol.com and ask for the "WAY_TO_GLOW"  #830 safety armband. It
seems to have a better potential for boaters than leds. No?

<A company named  OccuNomix Int. Inc. markets a flashing safety armband made from an electroluminescent strip powered by 2 AAA bats. that operates for more than 225 hours and is visible up to 5000 ft.>

Two thoughts: have worked at sea with similar types of electroluminescent devices before, trying to use them as part of distress signals for flight data recorders.  They take those little AAA batts and get one helluva lot of voltage to operate the chargers, and you can get one helluva shock from those little guys.  Mine were powered by nine volt cells, and one almost knocked me off the crash boat.

The more important point, as has been hashed and rehashed on PaddleWise in the past --- strobing or flashing lights, other than on nav markers, are distress signals, not neat things to wear so power craft will see you.  Same applies to flashing LEDs.  We're all better off if everyone uses standard issue white lights for signaling, per USCG standards (in the US, obviously) and not get fancy with strobes, flashing LEDs and light sticks.  There are well publicized lighting rules for all size boats, and we, as a community of sea kayakers, would be well served if everyone would just live with the rules and not be too creative in our electrics.

My understanding of blinking lights in the marine environment is that they
are the universal sign of distress.  I.e., nautical protocol requires other
boaters in the area to approach the blinking light assuming someone  is in
trouble.  May not be the signal we wish to send out.

Just a thought...

    I just picked up a PFD light at a local EMS here in Central NJ.  Called
a C-Light, made by  ACR Electronics in Ft. Lauderdale, FL.
www.acrelectronics.com  for the website..
    Basically an orange  waterproof 2-AA cell light which twists to turn on.
The front lens has a penlight forward lens for the usual stuff, and it is
surrounded by a donut lens which sends the light out in a 360 deg. circle.
Comes with a pin type arrangement and a velcro strap to attach to the
shoulder of your pfd.  I tried it out on the back so I don't get the light
in my eyes and had no difficulty turning it on or off.  Ten bucks.

It's a great light for a PFD.  You can also make a socket from the local plumbing supply from a PVC pipe endcap and mount it on your after deck on a recessed fitting machine screw.  Back there, it gives you about 330 degrees of coverage with a bright, semi-directional white light, and use a waterproof flashlight as your forward-showing light.  Gotta have someone with you to turn it on and off, but that's the only hard bit.

Have used ACR C-lights to mark expensive deployed electronics gear at sea during testing sequences, and have always had good luck with them.  And ACR always stands behind their products, too --- even slightly out of warranty strobes!

These work great - 

A lot of our more experienced club members where them pinned high on the
back of their pfds for night paddling.
Also cheap at 9.95 around here, and mine has been waterproof for over 6
years or so.  It uses 2 AA batteries, which hold enough juice (I use
rechargable ones) for about 8 hours.

My personal favorite is still the Krill light. It sells for $27.50 but
the 180 puts out a lot of light for 50 hours on two AA's. The laser stik,
LED light at $10 is nice too. Both avail. at diversdirect.com, plus a lot
of other nice waterproof stuff of use to paddlers.
