Cheap and easy protection for solar landscape lights. Drill a 1" hole as deep as your spade bit will go, and drop in your light. Now they won't fall prey to the mower, weed wacker, or clumsy people. Great for walking paths, or around the fire pit.
Great idea: String lights around a deck or outside space to add a romantic, swanky feel when they are turned on at night. They remind me of a fun restaurant on the coast with lots of dancing and good times.
