If you can solder wire to circuit boards and drill holes you can make your own.

Be sure and look at his single and triple LED headlights.
He does not provide links to LED's and optics because there making huge jumps in light output every few months. Last year light output for a single power LED was 45 Lumen. SSC introduced the new P7 C-BIN just a couple of months ago with 900 Lumen output. The P7 is not suitable for use with a bicycle dynamo. The Cree XR-E is with near 200 Lumen produced at 500mA each. Here is the link for the Cree XR-E LED.

Make sure you order optics for lambertian type LED's as thats the style sold by DX. Also make sure you get the holder as well.
