Solar take the energy of the sun and charges tiny batteries within the light during the day that keep the light lit up in the night. These lights are not as bright as the ones that tap into the electric lines but they are very good and good for energy savings as well. You should compare solar with other types of post cap lights to see which one will work best for your area before you buy. Either way, you will love having light on the posts outside for the safety it brings as well as the fun!

Traditionally, post caps are used to top off and protect the fence or deck posts and come in an assortment of styles and made of multiple materials. Finials normally sit atop the cap and are more ornate in nature. They too are made of many different materials and come in assorted shapes and sizes. I have also seen post caps and finials used as candle holders, centerpieces and stand alone decorative pieces as they bring architectural elements into an area in a very understated way. I suggest you look and see if this would be a way to finish off an area that is just lacking a little polish.
