Amber Xenon Flasher and the Cateye LD-1000, which I videoed tonight.
The Amber Xenon Flasher is spec'd to run on a 12 Volt DC R/C Car battery. I happened upon a slightly less powerful battery (which was much cheaper) at RadioShack, which is what I am using now. In spite of not using the full 12 VDC, the Amber Xenon Flasher works great.
I feel safe having these two lights on my commuter. The Gikma has the Dinotte 140R-AA taillight.
What is your setup like?
