For nearly 15
years, this list has been invaluable to me, and it has been
very seldom that I've been able to give anything back. But, I
hope this helps.
mpja.com
has 10W LEDs for $2.95 each. Each strobe takes three of
them. You also need the 30W power supply for each strobe.
Another $8.95. I've put a scope on the input and output. It
doesn't generate much in the way of noise. Just a constant
current.
There
is a seller on Ebay selling "Grimes wingtip light". You can
get two for $16 or one for $6.
In
America, any of the chain auto parts stores carries the EP36
flasher from Novita. Takes one for more strobes than you'll
want to run.
Battery -> Strobe switch -> EP36 ->
Input to each of the power supplies -> three LEDs in series
-> back to power supply -> back to EP36 -> ground
Once
set up, connect to a battery, but do not look directly at this
beast.
For my
first pass, I cut a strip of aluminum, 1"x3.5". Folded into a
triangle with 1" sides. Rivet an LED to each side.
To fit
it in the wingtip light, I'm cutting a piece of aluminum sheet
to replace the bulb and rivet to the housing. Where the light
was, I'm cutting the aluminum and letting it fold up from the
center to form three mounting faces where I'll rivet the LEDs.
