On the page for the
Outbound Lighting Detour, they have a link to their
Action Camera Quick Release Mount.
I can't personally vouch for the product, but I have seen some very positive comments about their lights.
I currently use a relatively large, relatively heavy headlight that mounts on the bars. If I wanted to go underneath an "out front" mount, I think the Outbound lighting is the slickest setup I've seen.
