Colors are nice but it doesn't work properly It could be the output voltage of your power box but when I first connected it to my car the blue one worked fine but noticed that the USB -Part got very hot so when I tried to use it again the lights didn't come on, I had to plug and unplug it several times but then the lights wouldn't go off until I unplugged everything! My biggest concern is the USB part overheating which could potentially pose a fire hazard! Don't trust them in the house unsupervised. The green gets a little warmer and the light doesn't go out until you fully unplug the cord.
