Unfortunately I didn't have a chance to have a closer look at it before disappeared inTO the endless space of the internet again, but iirc that light mount mimicked the shape of the factory unit, just with a linear slant in the front, meaning it would stick out even less than the factory piece. The lights were recessed a bit. If built heavy enough, this could actually work as a slider to help lifting the front end over ledges and rocks, not unlike some of the roller set-ups available out there.
For me off-roadability is not much of a concern (on my '15JK; for hard wheeling I have a '98 TJ), as my JK spends the vast majority of its time on pavement. I use it for work, and I routinely drive the entire night through areas where wild-life collisions are normal. There is no such thing as too much light for me; however, here many jurisdictions are actually enforcing the law that no aux. lights may be mounted higher than the OEM headlights, so all those set-ups that use mounts on the hood, the bottom of the windshield or the top windshield frame are off-limits to me. I already have two flood lights hanging below a hoop bar on top of the front bumper. My vanity does not allow me to mount more lights in front of that iconic grille, and of course square or rectangular lights are off-limits, as well. That tray/approach plate seems to meet many of my wants and needs, and that is why I would like to have a second, closer look at it....if I ever find it again!
