Fence Cap Solar Lighting

I really wish Ring would make an actual fence cap solar light. I understand people have been using the step lights on fencing but it would be more ideal to post on top of the post rather than downward. As fences tend to extend further away from houses, and the presumed range of the bridge (depending on yard size) it would be neat if they could wire in some kind of (hidden) antenna relay so the ones close to signal can boost out to remote parts. This would probably use more battery power but I’m only looking to have the lights on for maybe 3-4 hours daily which should be enough to do this from a full days charge in the sun.
