Not to burst your bubble Ernest but for those less likely to put something like that together ... when at Oshkosh this year, I went to Aircraft Spruce booth
and a guy there was selling his own design of Nav/Srobe bulbs: a set includes one Red, Green White. All you do is remove the existing Grimes bulbs and replace the coloured Red/Green lenses with clear ones and insert his custom LED bulbs. No power supply required;
no extra wiring required – use the existing circuit at much less current ~1.2A Vs 6-8A for a standard set. They aren’t cheap: $318 normal price but I was very impressed and bought them at the show special of $286. When you first turn them ON they are normal
NAV lights; turn them OFF for 1-2 seconds then back ON and they begin to strobe. Spruce part number is 11-14934 ... http://www.aircraftspruce.com/catalog/elpages/navstrobesextant40.php

Too much typing. Try the youtube video I made. Linked below. Everything is put together with A3 pulled rivets.

Pictures please. Having a hard time visualizing three LEDs creating a 180 degree dome mounting them in a triangle.
Is it possible to dim them to use for landing lights?

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.
