Here is some info on the LED lights! Each crystal comes with a small LED tealight that can be set to flicker like a candle, flash or have a steady glow. It is turned on with a button at the top of the tealight itself and is then snugly placed into the crystal. You can also use a remote control for these lights if you want more convenience ( buy it here) . These light up with a soft ethereal purple ember or a bright teal.
The lights work using a small button at the top of the LED itself. Sometimes you have to mash the light with your nail to get it to turn on. Make sure the light is screwed tight and batteries are oriented properly ( + side down) . You may have to replace the batteries soon after receiving your light- i have started to mail them with the batteries removed to avoid draining! If your LED gets set back into the light casing to far and you have trouble removing it, use a pair of flat pliers to grab the middle ridge on the underside of the LED to pull it out.
