Cyclemax Ohio has those if your interested. I installed those and the wiring is so thin that after about one year they started to deteriorate and started failing. So I took mine off and will not use again. Cool idea, but did not last, but I was riding 400 miles a week commuting, so may last longer if you don't ride that much.
P/S that was for the small Low Brow, not the light at the bottom.
