These solar light will look amazing for your July 4th party. You can put them anywhere you want to, inside or out such as a road, yard, window, workshop, or if you want to create a warm and romantic night with that special someone. They are energy efficient and environmentally charged by solar energy. There is a solar powered panel with a 20 cm garden spike. The long working time will continuously work more than 8 to 10 hours at night if the panel absorbs enough sunshine throughout the day. There are two switch buttons, one is mode (flashing mode convert switch,) and the other is power on/off, (after the switch is turned on, it will automatically light, control, and charge.) These are weather resistant for indoor or outdoor use.
