What a wonderful way to light up the night in the miniature garden! String the lights up along an arbor, light up a tree or hang them on a fairy house for special occasions. There are four different colors to choose from: Cool White, Ambient White, Blue, and Red. The indoor light string requires 3 AA batteries (not included) and includes a 6 hours ON/18 hours OFF timer feature. Each string is 36" long with 18 lights (spaced about 2" apart). Lighted wire strings are submersible in water, but battery pack is not waterproof so it needs to be protected.
