The JB Hatch highway pegs mount there so I could certainly see that it would be possible to make a mount that held a light instead of a footrest.
The Hatch pegs just have a flat steel arm that uses a regular bolt to screw into the tipover. I'm not sure if you could have it go under and out the front. You may need to follow the path of the Hatch pegs mount. Honestly, it may be possible to use the standard Hatch mount to secure a light to.
If you could make it work you would know it would not interfere with lean clearance or a fall.
The only thing I don't know what to do with would be the wires for power.
