I did this from the ground up. Since I use a venerable Kirtland handlebar bag on my Spectrum touring bike, I had the fork built with a single water bottle mount brazed on the fork blade about 2 inches below the crown. I cut a piece of old handlebar to make a screw on mount and then have a Cateye headlight mounted to that piece of handlebar. IMO, you're always better off with a higher mounted headlight. With that said, this performs fine, with no shadow issues, so it meets the mission requirements.
