Nice work Ernest. I would certainly go this route if I hadn't already spent a sickening amount of money on a certified Whelan lighting system all those years ago.

Back when I first built a few guys were trying to roll their own DIY led systems, but the tech just wasn't there yet. And IRC, TransportCanada had/has some goofy rule that if you choose to put lighting in your homebuilt aircraft, it had to be certified.

I wouldn't bother following that rule today, however in an irresistible urge to keep throwing good money after bad, I did recently buy the whelan led replacement bulbs for my system.

In other news...

I'd hoped to be back in the air by now, but my province of BC is burning with entire cities being evacuated. Our airport is home to a tanker base which has become extremely busy due to another city's tanker base relocating here due to wildfire evacuations.

So the last thing they need is a yahoo like me buzzing around the circuit. So I'll probably not get back in the air until the fall rains make flying less fun.

I guess I'll just go fishing again...

31325 OP and 31559 PS?

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.
