Latest project ....
A reflector with light for my narrow-gauge locomotives.
The diameter of the reflector is 4 mm.
The LED is 0.5 x 1 mm!
The reflector is made out of aluminum from oven trays.
I took a nut of the right diameter and slowly pushed the aluminum with the rounded top of the hat from a ballpoint pen.
Then I rough cut the edges and filed it to shape with a needle file.
I then drilled a 0.8 mm hole in the center of the reflector.
I glued the LED to the backside of the reflector with epoxy.
The LED is a bit too white, so it'll get a drop of Tamiya transparent orange.
Then I'll take Microscale Crystal Clear and fill the reflector so it gets a lens.

Nice. Do you wire the LEDs, or buy them with leads attached?

Nice job! Looks very fiddly, I think I'd have trouble doing that with my eyes the way they are... or at least I'd have a headache after doing it!
What I've done in the past is to sand the reflective material off the back of an MV Lenses lens, and then attach the surface-mount LED to the back with UV curing resin. Then I set the lens in the headlight mount with more UV resin (Bondic or similar).

Thanks all, I bought the LEDs on eBay. Search for 0402 LED with microlitz wire.
