Finn, why would you dim marker lights? Is there an upper limit on how bright the markers can be? There ARE limits on what area each can cover. I handled this by designing the mount to block light from where it isn't supposed to be. You could also use the 5W LEDs for markers. That's what I have, because the 10W weren't there when I put the markers together. But, I'd really like to know why you want to dim them. I'm wondering if I'm missing something.

Great, but the while point is cheap!
Three strobes (wings and tail) plus position lights and possibly
landing/taxi lights for less than $100.
If I could just figure out how to dim these LEDs for position
lights.

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.
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.
