In comments below there was inquiry into pictures of my lights. I haven't taken any yet but perhaps tonight I will. In the meantime here is a diagram and a schematic for those of you who might be interested. Leds are K2 Luxeon stars. The buckpuck is one that handles 1000ma and allows strobing and 5-32 volts. The Bridge Rectifier is a cheap one from Radio shack that is pretty much the smallest one they have. This light approaches the E6 in brightness but also gives some "be seen light" to the front and sides and really illuminates signs well.
Below is the schematic for you electronic nerd types (note I am not an electronic nerd type per se but play one on on the hobby bench when a need arises)-
