These are NOT just fairy lights stuffed inside! These are handmade lights, with strong soldered connections. This item is handmade, and may have small imperfections. Please allow 5-7 days for build!!! I sell through other outlets, and I get busy :) thank you for understanding. USB powered Blue Raspberry Prime Bottle night light. Made from ALL upcycled materials, including the wires, USB plug, resistor, the bulb, and of course the bottle! It is handmade, not machine made, so be aware of imperfections. Includes one blue LED mounted inside of the bottle, with the USB cable sticking out of the back. ( Wall Warts NOT Included ) Just plug into any USB outlet, and leave on for as long as you like :) ( NO need to change batteries , you can even use it as a car light ) There is a resistor near the USB plug which is visible through the heat shrink tubing. This is there to keep the 5 volts from the USB power source from burning up the 3 volt LED bulb, and it also creates a slight pause of about half a second when plugging in, so don't fret. Please do not mess with the circuitry or try to pull apart as this will void everything :/ There is NO on/off switch , just plug and unplug! If you want a different color LED inside of it, we can accommodate that :) just choose in the variations tab. The colors available are Blue, Green, Pink, White, And Violet. Blue looks the best!
