Dollar Tree stores are selling Christmas House LED Light Sets that run off two 1.5 Volt AA batteries (with holder and on/off switch) for a dollar. They are available in sets of either red, white, yellow, or blue. Make sure you look at the circle showing the color lights in the package! Also in the smallest print size possible above the circle the color is stated. The lights are spaced 4 inches apart and the wire to the battery box is about 7 inches. The wire is shrink wrapped 1 inch from the tip of the LED. Opening the battery box is a challenge as you need a #0 phileps head screwdriver with a set of plyers on the shaft to get the thing out! Once the screw is out, the top pops off. The switch works pretty good. For a BUCK how can you go wrong? God bless those little Chinese children. The colors of these LEDs is nice.
