Product introduction and Precautions Unlike other lights, our solar ground lights consist of larger solar panel, which means better use of solar energy into electricity. Besides, built-in sensitive light sensor, these solar path lights automatically turn on at night and turn off at dawn or in bright places. (Please make sure to "turn on" the switch before use). Before using the support, it is best to loosen the soil with a shovel and dig a suitable hole in the support (so as not to push it directly into the support and damage the support). Please keep the solar panels as clean as possible (dirty solar panels are not conducive to solar storage). For best results, install the light in a place where there is direct sunlight and no obstacles. (Avoid installing it on eaves, trees, window sills and other places with shadows and obstructions. During the day, the more sunlight the solar ground light receives, the longer the night time). If there is no strong sunlight or in winter, it may take longer to fully charge.
