Pookie,
  In the poll are you asking if people have one, would be interested in one, or know how to make one?
  It would not be too hard to make one from a 555 timer chip, and the output could drive a couple of transistors running the LEDs.
  What do you mean by strobe? Do you just want two LEDs alternating (each on 50% of the time), or do you mean one LED pulsed, then a delay, then the other pulsed, then a delay, etc etc? Being an electronic engineer I may be able to design something up for you if you like.

I have already make a 555 alt flasher, but was more after the same but strobing the leds,
I have ended up buying a showme mulii strobe unit in from the USA, as there isnt much on the web for strobing leds, only to alt flash them.
