Thanks for the video Ernest.

How do you dim them?

I'm looking at the 10W red, green and white LEDs for posittion 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.
