A:  My fence posts were a little bit too large for cap to fit correctly. I filed them down a bit then used the screws to tighten onto the post.

A:  It just sits on the post and is fastened with 2 included screws.

A:  Use small screws in the bottom of the lights to anchor the light to top of post. Must cut top of post so it is horizontal. Slide light over top of post before applying screws. 

A:  In my experience it needs to be in direct sunlight, or else it won’t charge properly. 

A:  Direct light is preferred, but indirect light will charge it enough for several hours of light after sunset. It’s unlikely you’ll get much of a charge if it’s in shadows most of the day.
