Night Lights are excellent sources of alternative light for use during power outages, portable lighting (camping etc.) and they are also great for use in areas that can be dangerous for conventional alternative lighting. You can even use them under water. Best of all, there are no batteries to worry about.........Completely non-toxic and self activating....just break and shake! Night Lights will be picked and shipped at random colors if purchased individually. If you want all colors you need to purchase more as ordering one will only get you one. Comes in 8 different colors: Orange, Green, Red, Yellow, Blue, Purple, White, Yellow-Green.
