I love solar lights.  These are fun because you have a choice of color or just the yellow light.  You have the choice of flipping the switch either way.  Put the stake on and place them around the yard where you want the ambiance to be.  It helps to see around the yard at night when it's pitch-black outside.  The fun part when you have them on color is that they rotate from each color--they dim and then they have an explosion of color and repeat to the next color.  Fun addition to my yard.  The price was good on the Labor Day sale.
