We take 5 solar lights and a home made one with us every time. The 5 we take are apr 4-5 years old and were the $2.49 ones you get at any variety store. The home made one is made up of a larger type solar light. About 3-1/2" dia. You can twist the tops off most of them, so I removed the top and installed it on a large round plastic container jar. The type with the locking top. I painted the inside of it for color. We set it out during the day and bring it in at night and use it in the bathroom for a night light. It will stay on for a long time. It is also the type that requires an AA battery. The battery lasts several years. We usually set the other 5 solar lights out at various spots at our site. Usually by a stump or rock. We don't like bright lights at night and the solar lights are really just locator lights. We don't use the porch light either and have two lights with magnets attached that we put on the steps. They all give us a point of reference when walking in the dark. Plus we like the ambiance.
