Get them while you can, because it is likely when we're out we will never be able to offer these units again. The new color or wire appears a foggy white when off, but when turned on it's a bright ICE BLUE. This is a pure blue, not greenish or purplish hue. We call it ICE BLUE, but SKY BLUE would also describe it well as it is nearly the color of a sunny blue sky. The wire is much stiffer and plastic like than out normal Cool Neon wire, but it seems to be very durable resistant to kinking. and The driver has an on/off button and a switch for constant glow or blink and takes 2 AA batteries.
