Thanks for posting Fred. It looks like your lights do a great job of illuminating your path at night.
About 10 years ago my friends and I found ourselves finishing up a single track trail in the dark. We were poor college kids with old and semi-functional bikes. The only lights in the group that worked were my right blinkers, and they fluctuated speed amd brightness based on engine speed. Luckily it was not too far back to the trailhead and we survived to back more bad decisions another day.
