This idea is very appealing to me. I currently have a PDW Fenderbot taillight, and I'd like to put an LED behind the reflector in it, much like in the link above. I don't like the idea of using a white LED in the taillight, however, and I also don't have to deal with quite the same space restrictions as the instructions in the link above, since I'm not trying to put an LED into such a small, flat reflector.
DIY website you linked to and the RADbot has ZERO heatsinking. I recommend some heatsinking at least.
