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.&n= bsp; Another $8.95.  I've put a scope on the input and output.&nb= sp; 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 lig= ht 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.
