GoPro Accessories for my mount

Howdy y'all!

I'm trying to find a go pro mount for my outbound light, my current setup doesn't hold the light stable and moves down. My current 3 way adapter seems to be to thin on the outside

I found that my GoPro mounts holds the light really well. The GoPro 3 way mount is thicker and that seems to be the reason for the stable hold

Any recommendations or ways to help

I'm also willing to change my mount as long it hold both light and bike computer!
