Why I Designed It

Many solar fence lights are made for larger posts and do not fit standard 70 mm fence posts. At the same time, not every post needs a light.

This design solves both problems by providing:

1. A protective cap for all posts.
2. An adapter version that allows larger solar lights to be mounted securely.
3. A matching standard cap for locations where lighting is not needed.

This keeps the entire fence looking consistent while giving you complete freedom to choose where lights are installed.
