The Touch Of ECO CAROLITE PRO is a solar powered flameless window candle that automatically turns on every night and charges each morning. The CAROLITE gives you classic holiday ambiance without any electric bill or the hassle of plugging in your lights every night! Simply lock the CAROLITE PRO suction cup against the inside of your window and turn them on (either flickoring or steady mode). Allow the high performance solar panel to absorb direct sunlight through the day. At night the LED tip will automatically illuminate and flicker like a real flame. The CAROLITE PRO produces 6-8 hours of beautiful holiday lighting each night. You can also stand the candle upright on any flat surface for mobile holiday lighting!
